摘要

采用紫外可见吸收、稳态荧光光谱和荧光衰减测量技术

观察了4-硝基-4'-氨基偶氮苯(NAA)在氯仿溶液中的光致变色现象及分子的跃迁能级和能级寿命。结果表明:NAA分子的顺反异构化反应并非一级反应;分子处于反式异构体和顺式异构体的跃迁能分别为255.6

240.2 kJ/mol;分子处于反式异构体的能级寿命为0.02 ns

处于顺式异构体的能级寿命为3.54 ns。顺反异构体的含量、NAA分子之间及NAA分子与溶剂分子之间的相互作用影响NAA分子激发态的能级寿命。

Abstract

The UV-Vis absorption spectra

steady-state fluorescence spectra and the fluorescence decay curve of 4-(notro)-4'-(amido)-azobenzene (NAA) in chloroform solution were measured. The photoinduced color changing phenomena were investigated. The transition energies and the excited state lifetime were observed. It was found that the reaction of NAA photochemical Cis-tran-isomerization is not a first-order reaction

and it is very complex. The transition energies for trans-and cis-isomers are 255.6 kJ/mol and 240.2 kJ/mol. The excited state lifetimes for trans- and cis- isomers are 0.02 ns and 3.54 ns. And it is influenced by the content of trans- and cis- isomers and the interacting of NAA molecule to NAA molecule or to the solvent molecule.
