摘要/Abstract

摘要： 利用UV-Vis吸收光谱仪和光化学反应器研究了新型双发色团固体激光染料薄膜的光降解动力学.研究结果表明:双发色团固体激光染料薄膜的光褪色反应遵循假一级动力学衰减.在PRNAM系列共聚物(N-烯丙基-若丹明1、N-[(2-丙烯酸基)乙基]-1,8-萘酰亚胺和甲基丙烯酸甲酯的共聚物)中萘酰亚胺基团通过聚合物碳链与若丹明基团的氮原子相连;而在PRNM系列共聚物(若丹明1的烯丙基酯、N-[(2-丙烯酸基)乙基]-1,8-萘酰亚胺和甲基丙烯酸甲酯的共聚物)中则是与若丹明基团的酯基相连.PRNAM系列共聚物的光稳定性优于PRNM和PRM(若丹明1的烯丙基酯和甲基丙烯酸甲酯的共聚物)系列的光稳定性.

Abstract: Modified rhodamine 6G molecules (Rh-Al or Rh-Aln)with polymerizable double bonds had been copolymerized with 1,8-naphthalimide derivatives.We report on their photostability in solid film.The photodegradation kinetics of novel laser copolymers based on modified rhodamine 6G and 1,8-naphthalimide has been studied by UV-Vis absorption spectroscopy.The results show that the rates of the photofading reactions of the novel laser copolymers follow quasi-first-order kinetic process.In copolymers PRNAM(N-ally-rhodamine 19/N-(2-acryloylethoxyl)-1,8-naphthalimide/methyl methacrylate copolymer),naphthalimide moieties are connected to rhodamine moieties at nitrogen atom of rhodamine moiety, and naphthalimide moieties are connected to rhodamine moieties at ester group of rhodamine moiety in copolymers PRNM(ally ester of rhodamine 19/N-(2-acryloylethoxyl)-1,8-naphthalimide/methyl methacrylate copolymer).The photostability of PRNAM is far superior to that of PRNM and PRM(ally ester of rhodamine 19/methyl methacrylate copolymer).
