摘要: 通过酚醛树脂羟基活性基团与6-氯-5,12-萘并萘醌(1)接枝反应,制备了3种有光致变色性的酚醛树脂:萘并萘醌酚醛树脂(2),甲基萘并萘醌酚醛树脂(3)和氯代萘并萘醌酚醛树脂(4).在四氢呋喃(THF)溶液中,3种光致变色聚合物有与6-苯氧基-5,12-萘并萘醌相似的光致变色行为.同时,发现聚合物骨架上的取代基对聚合物的变色速度影响较小,聚合物的平均分子量影响聚合物的变色速度.

Abstract: Three naphthacenequinone photochromic phenolic resins, naphthacenequinone phenolic resin(2), methyl-naphthacenequinone phenolic resin(3) and chloro-naphthacenequinone phenolic resin(4) were synthesized by an one-step method, i.e. the reaction between 6-chloro-5,12-naphthacenequinone(1) and phenolic resins. The polymers have similar photochromic properties in THF solution with photochromic compound 6-phenoxy-5,12-naphthacenequinone. It was found that the substituents attaching to the main chain backbone of the polymer have a slight effect on the reaction and rate of photoisomerization of polymers. The rate constants were influenced by the molecular weight.

Key words: Naphthacenequinone, Phenolic resin, Photochromism, Photoisomerization
