Abstract

Abstract Photochromic compounds are well known and attract tremendous necessity for their versatile applications in various fields of science. When exposed to light, metal complexes containing potentially photoswitchable azo (–N=N–) and imine (–C=N–) based ligands can be switched between trans (E) and cis (Z) two isomers, as well as energy manipulation and energy level modulation. Then the cis (Z) isomers underwent slow thermal isomerization back to the more stable trans (Z) isomers. The quantum efficiency of metal complexes has been tuned by modifying the ligands’ structures and altering metal substrates. Herein our review encompasses the photochromic behavior of a few conjugated azo-imine (–N=N–C=N–), ligands such as arylazoimidazoles, phenylazopyridine, azobispyridine, arylazopyrozoles, as well as a few non-conjugated azo-imine or Schiff base ligands with their metal complexes.

共轭(- N=N -c =N -)和非共轭偶氮亚胺配体中金属配合物的光致变色行为综述
摘要:光致变色化合物因其在各个科学领域的广泛应用而受到广泛关注。当暴露于光下时,含有潜在可光切换的偶氮(- N=N -)和亚胺(- c =N -)基配体的金属配合物可以在反式(E)和顺式(Z)两个异构体之间切换,以及能量操纵和能级调制。然后顺式(Z)异构体经过缓慢的热异构化反应回到更稳定的反式(Z)异构体。金属配合物的量子效率是通过修饰配体结构和改变金属底物来调节的。本文综述了几种偶氮亚胺(- N=N -c =N -)的光致变色行为,配体如芳唑并咪唑、苯并吡啶、偶氮双吡啶、芳唑并吡唑,以及一些非共轭偶氮亚胺或席夫碱配体及其金属配合物。
