3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Electric Literature of C7H7NO4

NIR light and enzyme dual stimuli-responsive amphiphilic diblock copolymer assemblies was written by Wang, Jilei;Wu, Bing;Li, Shang;He, Yaning. And the article was included in Journal of Polymer Science, Part A: Polymer Chemistry in 2017.Electric Literature of C7H7NO4 This article mentions the following:

Using atom transfer radical polymerization (ATRP) and macromol. azo coupling reaction, both o-nitrobenzyl (ONB) group and azobenzene group were efficiently incorporated into the center of the amphiphilic diblock copolymer chain. The prepared diblock copolymer was well characterized by UV-vis, 1H NMR, and GPC methods. Self-assembly of the amphiphilic copolymer in selected solvents can result in uniform self-assembly aggregates. In the presence of external stimuli [upconversion nanoparticles (UCNPs)/NIR light or enzyme], the amphiphilic diblock copolymer chain could be broken by the cleavage of ONB or azobenzene group, which would lead to the disruption of the self-assembly aggregates. This photo- and enzyme-triggered disruption process was proved by using transmission electron microscopy (TEM) and GPC method. Fluorescence emission spectra measurements indicated that the release of Nile red, a hydrophobic dye, encapsulated by the self-assembly aggregates, could be successfully realized under the NIR light and enzyme stimuli. © 2017 Wiley Periodicals, Inc.
