摘要：以8-羟基喹啉、甲醛和苯胺为原料,制备了5-[(苯胺基)甲基]-8-羟基喹啉,并以此为单体,以过硫酸铵作为氧化剂,采用化学氧化聚合法,在酸性水溶液中合成了聚N-[5-(8-羟基喹啉)甲基]苯胺。通过正硅酸乙酯表面修饰聚N-[5-(8-羟基喹啉)甲基]苯胺获得了具有荧光特性的聚N-[5-(8-羟基喹啉)甲基]苯胺/硅杂化材料。该杂化材料不仅在480 nm附近发出较强的荧光,而且在强酸和弱酸电解质溶液中均表现出了较好的氧化-还原可逆性。
Poly-N-[5-（8-quiniolinol）ylmethyl]aniline was synthesized by the chemical oxidative polymerization of 5-（anilinomethyl）-8-hydroxyquinoline,which was synthesized from aniline,8-quinolinol and methanal,using ammonium peroxydisulfate as an oxidant.Then,poly-N-[5-（8-quinolinol）ylmethyl]aniline/silica hybrid with fluorescence property was prepared via the surface modification of poly-N-[5-（8-quinolinol）ylmethyl]aniline using tetraethyl orthosilicate.This hybrid not only shows a strong visible emission centered at 480 nm,but also has good redox reversibility in both strong acid and weak acid electrolytes.
