新型聚方酸菁功能材料的合成及其性能研究

Study of the Synthesis and Performance of New Polysquaraine Materials

以对苯二酚为起始原料,经Wittig-Horner等反应合成了主链结构的二吡咯化合物(5a和5b);5a或5b与方酸经聚合反应合成了两种新型聚方酸菁材料BPEBP(6a)和BPVOD(6b),其结构和性能经1H NMR,13C NMR,IR,MS,TG,UV-Vis和FL表征。结果表明:6a和6b的初始分解温度分别为282.0℃和293.8℃;λmax分别位于732 nm和865 nm;λem分别位于478 nm和428 nm。

The main chain structures of two pyrrole compounds（5a and 5b） were synthesized by Wittig-Horner reaction,and so on using 1,4-benzenediol as the starting material.Two new polysquaraine materials,BPEBP（6a） and BPVOD （6b）,were synthesized by polymerization of squaric acid with 5a and 5b,respectively.The structures and performances were characterized by 1H NMR,13C NMR,IR,MS,TG,UV-Vis and FL.The performance of 6a and 6b were as follows：The initial decomposition temperature were 282.0 ℃ and 293.8 ℃ ; λmax were 732 nm and 865 nm; λem were 478 nm and 428 nm,respectively.
