摘    要: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-蔡啶,PAA5-PAMN2(PAMN是2-phenmethy-lamino-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342nm.Zn(OAc)2,的加入致使PAA5-PAMN,水溶液的荧光猝灭,而当OAcˉ改变为NO3ˉ时,在荧光强度不断降低的同时,由于NO3ˉ离子的配位使最大发射波长从410nm蓝移到400nm.Na^+离子对其没有明显的荧光猝灭效应,

关 键 词:水溶性聚合物  1  8-萘啶衍生物  Zn^2+离子  光谱

Abstract:A novel water-soluble polymer containing poly acrylic acid and 2-phenmethylamino-7-methyl-1,8-naphthyridine was prepared and its structure was determined by spectroscopic analysis and density functional theory(DFT) calculation.The electronic absorption spectra of the polymer in acid or alkaline water solution show absorption maxima with peaks at 364 and 342 nm,respectively.The addition of Zn(OAc)2 to the H2O solution of PAA5-PAMN2 results in the quenching of the fluorescence emission centered at 410 nm.However,with Zn(OAc)2 changed to Zn(NO3)2 the emission maximum of PAA5-PAMN2 in water solution was blue-shifted to 400 nm but with a concomitant decrease of emission intensity,which is tentatively suggested to originate from Zn2 coordinated to PAA5-PAMN2 and NO3-.The effect of Na ion on emission was not observed.
Keywords:water-soluble polymer  1  8-naphthyridine derivative  Zn2  ion  spectroscopy
