Abstract: 本文制备得到一种新型萘啶基的水溶性光致发光聚合物:聚丙烯酸(PAA)-2-苄氨基-7-甲基-1,8-萘啶,PAA5-PAMN2(PAMN是2-phenmethylamino-7-methyl-1,8-naphthyridine的缩写),经光谱分析和密度泛函理论计算,研究了化合物的结构和组成.这种聚合物在酸性和碱性条件下呈现最大的吸收波长分别为364和342 nm.Zn(OAc)2的加入致使PAA5-PAMN2水溶液的荧光猝灭,而当OAc-改变为NO3-时,在荧光强度不断降低的同时,由于NO3-离子的配位使最大发射波长从410 nm蓝移到400 nm.Na+离子对其没有明显的荧光猝灭效应.
