A UV-Cleavable Bottlebrush Polymer with o-Nitrobenzyl-Linked Side Chains was written by Zhu, Wen;Zhang, Liangcai;Chen, Yongming;Zhang, Ke. And the article was included in Macromolecular Rapid Communications in 2017.Formula: C7H7NO4 This article mentions the following:
An UV-cleavable bottlebrush polymer is synthesized using the “grafting-onto” strategy by combining living radical polymerization and copper-catalyzed azide-alkyne cycloaddition (CuAAC). In this approach, reversible addition-fragmentation chain transfer polymerization is used to prepare a poly(methylacrylate) backbone with azide side groups, while atom transfer radical polymerization is employed to prepare polystyrene (PS) side chains end-functionalized with o-nitrobenzyl (UV-cleavable) propargyl groups. CuAAC is then used to graft PS side chains onto the polymer backbone, producing the corresponding bottlebrush polymers with UV-cleavable PS side chains. The formation of the bottlebrush polymer is characterized by 1H NMR spectroscopy, gel permeation chromatog. (GPC), and Fourier transform IR spectroscopy. The cleavage behavior of the bottlebrush polymer is monitored in THF solution under UV irradiation by GPC and viscosity measurements. In the experiment, the researchers used many compounds, for example, 3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9Formula: C7H7NO4).
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. 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.Formula: C7H7NO4
