copolymerization with styrene or methyl methacrylate of the salts 1a−3a, 2d, and 3d produced (co)polymers 1e, 2e, 2f, 3f, 1g, 2g, 2h, and 3h. The photosensitive dipolar oxypyridinium or oxyisochinolinium betaine structures were generated in solutions with triethylamine from the low molecular weight and polymeric salt precursors. For the model compounds 1b−4b and (co)polymers 1e, 2e, 2f, 3f, 1g, 2g
聚合hydroxypyridinium和hydroxyisoquinolinium盐1A - 4a中,2D,和三维已从乙烯基苄基氯制备,或甲基丙烯酸缩水甘油酯和3-羟基吡啶(2),4-或5-羟基异喹啉(1,3),和8-羟基喹啉(4)。与苯乙烯或甲基丙烯酸甲酯对盐1a - 3a,2d和3d进行自由基均聚和共聚,生成的(共)聚合物1e,2e,2f,3f,1g,2g,2h和3h。在具有三乙胺的溶液中从低分子量和聚合盐前体中生成了光敏双极氧吡啶鎓或氧异吡啶啉甜菜碱结构。对于模型化合物1b - 4b和(共)聚合物1e,2e,2f,3f,1g,2g,2h和3h,在紫外线照射下检测到该甜菜碱结构最长的波长吸收的降解。紫外线对模型化合物N-苄基-4-羟基异萘啉氯化物(1b)在三乙胺存在下通过分子内环化产生预期的氮丙啶类结构1k。
