A photochromic phenoxyquinone-based, sensor for aliphatic primary amine was developed. An efficient trans-to-ana photoisomerization was occurred when 6-(4′-methoxyphenoxy)-5,12-naphthacenequinone in acetonitrile was irradiated with 365nm UV light. The photochemically generated “ana” quinone intermediate was found to undergo nucleophilic substitution reactions by aliphatic primary amines to afford...
Acrylate- and styrene-derived polymers having pendant phenoxyquinones for photochromism were prepared by 2,2'-azoisobutyronitrile (AIBN)-initiated radical polymerization. Synthesis of the monomers were straightforward and the polymers were obtained in high yields in spite of the quinone moieties presented in the monomers, which usually can function as radical scavengers and/or catalysts poison. Photo-induced...
