Controlled self-assembly into diverse stimuli-responsive microstructures: from microspheres to branched cylindrical micelles and vesicles was written by Zhou, Xiaoteng;Li, Lingxiao;Qin, He;Ning, Bo;Li, Junpei;Kan, Chengyou. And the article was included in RSC Advances in 2018.Application of 60463-12-9 This article mentions the following:

A series of amphiphilic PDMAEMA-SS-PCL chains with variable ratios of hydrophilic poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) to hydrophobic poly(蔚-caprolactone) (PCL) were prepared via ring-opening polymerization, in which the two different moieties were linked via a disulfide bond with reduction responsiveness. After crosslinking by the photodegradable o-nitrobenzyl linkage, the amphiphilic chains could self-assemble into microspheres, branched cylindrical micelles and vesicles, which were responsive to the reduction agent DL-dithiothreitol and UV light irradiation through different mechanisms. In the experiment, the researchers used many compounds, for example, 3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9Application of 60463-12-9).

3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Application of 60463-12-9

Light-Responsive, Shape-Switchable Block Copolymer Particles was written by Lee, Junhyuk;Ku, Kang Hee;Kim, Jinwoo;Lee, Young Jun;Jang, Se Gyu;Kim, Bumjoon J.. And the article was included in Journal of the American Chemical Society in 2019.Application of 60463-12-9 This article mentions the following:

A robust strategy is developed for preparing light-responsive block copolymer (BCP) particles in which shape and color can be actively controlled with high spatial and temporal resolution The key to achieving light-responsive shape transitions of BCP particles is the design and synthesis of surfactants containing light-active groups (i.e., nitrobenzyl esters and coumarin esters) that modulate the amphiphilicity and interfacial activity of the surfactants in response to light of a specific wavelength. These light-induced changes in surfactant structure modify the surface and wetting properties of BCP particles, affording both shape and morphol. transitions of the particles, for example from spheres with an onion-like inner morphol. to prolate or oblate ellipsoids with axially stacked nanostructures. In particular, wavelength-selective shape transformation of the BCP particles can be achieved with a mixture of two light-active surfactants that respond to different wavelengths of light (i.e., 254 and 420 nm). Through the use of light-emitting, photoresponsive surfactants, light-induced changes in both color and shape are further demonstrated. Finally, to demonstrate the potential of the light-triggered shape control of BCP particles in patterning features with microscale resolution, the shape-switchable BCP particles are successfully integrated into a patterned, free-standing hydrogel film, which can be used as a portable, high-resolution display. In the experiment, the researchers used many compounds, for example, 3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9Application of 60463-12-9).

3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application of 60463-12-9

Localizable and Photoactivatable Fluorophore for Spatiotemporal Two-Photon Bioimaging was written by Zhou, Liyi;Zhang, Xiaobing;Lv, Yifan;Yang, Chao;Lu, Danqing;Wu, Yuan;Chen, Zhuo;Liu, Qiaoling;Tan, Weihong. And the article was included in Analytical Chemistry (Washington, DC, United States) in 2015.Related Products of 60463-12-9 This article mentions the following:

Photoactivatable probe-based fluorescent imaging has become an efficient and attractive technique for spatiotemporal microscopic studies of biol. events. However, almost all previously reported photoactivatable organic probes have been based on hydrosol. precursors, which produced water-soluble active fluorophores able to readily diffuse away from the photocleavage site, thereby dramatically reducing spatial resolution Hydroxyphenylquinazolinone (HPQ), a small organic dye known for its classic luminescence mechanism through excited-state intramol. proton transfer (ESIPT), shows strong light emission in the solid state, but no emission in solution HPQ was employed as a precursor to develop a localizable, photoactivatable two-photon probe (PHPQ) for spatiotemporal bioimaging applications. After photocleavage, PHPQ releases a precipitating HPQ fluorophore which shows both one-photon and two-photon excited yellow-green fluorescence, thereby producing a localizable fluorescence signal that affords high spatial resolution for bioimaging, with >200-fold one-photon and 150-fold two-photon fluorescence enhancement. In the experiment, the researchers used many compounds, for example, 3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9Related Products of 60463-12-9).

3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group.

Formation of secondary organic aerosol tracers from anthropogenic and biogenic volatile organic compounds under varied NO_x and oxidant conditions was written by Sato, Kei;Ikemori, Fumikazu;Ramasamy, Sathiyamurthi;Iijima, Akihiro;Kumagai, Kimiyo;Fushimi, Akihiro;Fujitani, Yuji;Chatani, Satoru;Tanabe, Kiyoshi;Takami, Akinori;Tago, Hiroshi;Saito, Yoshinori;Saito, Shinji;Hoshi, Junya;Morino, Yu. And the article was included in Atmospheric Environment: X in 2022.Computed Properties of C7H7NO4 This article mentions the following:

For source apportionment by tracer method of secondary organic aerosol (SOA), the ratios of aerosol tracer to total SOA mass (fSOA) were determined during the oxidation of toluene, naphthalene, 伪-pinene, and isoprene by a series of laboratory experiments Seven anthropogenic SOA tracers maintaining an aromatic ring structure, including 4-nitrophthalic acid and 3,5-dinitrosalicylic, were newly investigated as a chamber study together with 21 traditional aerosol tracers of anthropogenic and biogenic SOA. Experiments of the OH-initiated oxidation of anthropogenic VOCs were conducted as a function of the initial VOC/NOx ratio. No significant dependence on the VOC/NOx ratio was observed for the fSOA of 2,3-dihydroxy-4-oxopentanoic acid from toluene and phthalic acid from naphthalene, whereas the fSOA of nitroarom. compounds such as 5-nitrosalicylic acid, 3,5-dinitrosalicylic acid, and 4-nitrophthalic acid increased with decreasing VOC/NOx ratio. Among seven newly evaluated anthropogenic SOA tracers, we concluded that 3,5-dinitronsalicylic can be used as a toluene SOA tracer, whereas 4-nitrophthalic acid can be used as a naphthalene SOA tracer. Results of kinetic calculations suggest that naphthalene is a major source of 5-nitrosalicylic acid under urban and rural conditions of previous observation studies. The ozonolysis and NO₃-initiated oxidation of biogenic VOCs were investigated in addition to OH-initiated oxidation of biogenic VOCs. As for biogenic SOA tracers such as pinic acid and 2-methyltetrols, the fSOA value measured for the NO₃-intiated reaction was lower than that of the OH-initiated oxidation and the fSOA value measured for the ozonolysis was not necessarily close to that of the OH-initiated oxidation These results suggest that daytime and nighttime biogenic SOA formation events are interpreted by using different sets of the fSOA values. In the experiment, the researchers used many compounds, for example, 3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9Computed Properties of C7H7NO4).

Synthesis, Characterization, and Application in HeLa Cells of an NIR Light Responsive Doxorubicin Delivery System Based on NaYF₄:Yb,Tm@SiO₂-PEG Nanoparticles was written by Alonso-Cristobal, Paulino;Oton-Fernandez, Olalla;Mendez-Gonzalez, Diego;Diaz, J. Fernando;Lopez-Cabarcos, Enrique;Barasoain, Isabel;Rubio-Retama, Jorge. And the article was included in ACS Applied Materials & Interfaces in 2015.Synthetic Route of C7H7NO4 This article mentions the following:

Herein, we present a phototriggered drug delivery system based on light responsive nanoparticles, which is able to release doxorubicin upon NIR light illumination. The proposed system is based on upconversion fluorescence nanoparticles of 尾-NaYF₄:Yb,Tm@SiO₂-PEG with a mean diameter of 52 卤 2.5 nm that absorb the NIR light and emit UV light. The UV radiation causes the degradation of photodegradable ortho-nitrobenzyl alc. derivates, which are attached on one side to the surface of the nanoparticles and on the other to doxorubicin. This degradation triggers the doxorubicin release. This drug delivery system has been tested “in vitro” with HeLa cells. The results of this study demonstrated that this system caused negligible cytotoxicity when they were not illuminated with NIR light. In contrast, under NIR light illumination, the HeLa cell viability was conspicuously reduced. These results demonstrated the suitability of the proposed system to control the release of doxorubicin via an external NIR light stimulus. In the experiment, the researchers used many compounds, for example, 3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9Synthetic Route of C7H7NO4).

3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used.

Photocleavage of Covalently Immobilized Amphiphilic Block Copolymer: From Bilayer to Monolayer was written by Gungor, Eda;Armani, Andrea M.. And the article was included in Macromolecules (Washington, DC, United States) in 2016.Reference of 60463-12-9 This article mentions the following:

We developed and verified a method to create a photocleavable smart surface. Using the grafting to approach, we covalently attached an intelligently designed tailor-made diblock copolymer to a silicon wafer. The photocleavable moiety, o-nitrobenzyl (ONB) ester, was integrated into the copolymer at the junction point between the hydrophilic poly(ethylene oxide) (PEO) and the hydrophobic polystyrene (PS) chains. The well-defined azide bearing amphiphilic block copolymer was synthesized via a general stepwise strategy that combines atom transfer radical polymerization (ATRP) and copper(I)-catalyzed azide-alkyne cycloaddition reaction (CuAAC), ending with azidation. The azide end-functionalized copolymer chains were covalently bound to the alkyne-immobilized silicon wafer by CuAAC. The smart surface was exposed to UV irradiation, resulting in photocleavage of the grafted ONB linker. As a result of the photocleavage and subsequent removal of the o-nitrosobenzaldehyde bearing PEO, the PS layer remained on the surface. To confirm the behavior, film thickness and wettability changes were investigated before and after UV irradiation using AFM and contact angle measurements. Integration of photocleavable polymers through covalent grafting to solid surfaces contributes responsiveness to such materials that can find a wide array of applications in advanced devices. In the experiment, the researchers used many compounds, for example, 3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9Reference of 60463-12-9).

3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Reference of 60463-12-9
