摘要:

以1,8-萘酰亚胺为原料,合成了两种含萘酰亚胺官能团的乙烯基单体(NAPa和NAPb)。通过核磁、元素分析、紫外吸收光谱等对化合物结构进行了表征。并以这两种化合物为单体,通过原子转移自由基聚合(ATRP)的方法合成了它们均聚物,用1H-NMR ,GPC等对均聚物的结构进行了表征。研究了单体及其聚合物在不同浓度、不同溶剂以及在聚合物薄膜中的激发和发射荧光光谱,考察了聚合物浓度、溶剂极性等对荧光的影响。结果表明,单体和均聚物都具有较强的绿色荧光, 均聚物的荧光量子效率(φPNAPa=0.34, φPNAPb=0.35)高于单体的荧光量子效率(φNAPa=0.25, φNAPb=0.27)。

Abstract:

Abstract: Two fluorescent vinyl monomers containing 1,8-naphthalimide segments were synthesized and polymerized utilizing atom transfer radical polymerization. The monomers and the homopolymers were characterized by 1H-NMR, and GPC, respectively. The photophysical properties of the monomers and homopolymers were studied in detail. Results show that both monomers and homopolymers had good fluorescent properties, the homopolymers had a higher quantum yield than monomer .

Key words: naphthalimide,atom transfer radical polymerization(ATRP),fluorescent property,quantum yield
