Kim, Hansol; Khazi, Mohammed Iqbal; Kim, Jong-Man published an article in 2021. The article was titled ãPreparation and colorimetric response of an aldehyde-functionalized macrocyclic diacetylene-derived polydiacetyleneã? and you may find the article in Dyes and Pigments.Category: alcohols-buliding-blocks The information in the text is summarized as follows:
Stimulus-responsive colorimetric materials have found great utility in a variety of fields including anticounterfeiting, display and sensor technologies. Herein, the authors describe a colorimetric polydiacetylene (PDA) that is generated by polymerization of the aldehyde-functionalized macrocyclic diacetylene, MCDA-CHO. UV irradiation of self-assembled MCDA-CHO generates a blue-color PDA, which undergoes a sequential blue-purple-brown-orange color change upon heating. Interestingly, the PDA displays a remarkably high temperature reversible thermochromism between 30 (blue) and 180° (reddish-brown). In addition to displaying reversible thermochromism, polymerized MCDA-CHO can be employed for colorimetric differentiation between aromatic and aliphatic primary amines. Accordingly, a blue-to-reddish brown color change takes place when the PDA is exposed to primary aniline derivatives while no color change occurs in the presence of aliphatic primary amines. IR spectroscopic anal. confirms that this colorimetric selectivity is a consequence of the facile formation of imine groups through reactions of the aldehyde moieties in the PDA with anilines. The results came from multiple reactions, including the reaction of 3,5-Dihydroxybenzaldehyde(cas: 26153-38-8Category: alcohols-buliding-blocks)
3,5-Dihydroxybenzaldehyde(cas: 26153-38-8) is a building block. It has been used in the synthesis of 2,4-dimethylbenzoylhydrazones with antileishmanial and antioxidant activities.Category: alcohols-buliding-blocks
