Two organic-inorganic iodoargentate hybrids, [(HPBI)·(MeCN)][Ag3I4] (1) and [MPBI][Ag3I4] (2) (HPBI+ = 1-proton-2-phenylbenzimidazolium, MPBI+ = 1,3-dimethyl-2-phenylbenzimidazolium), have been synthesized. They exhibit structure-dependent photochromism with fast response and wide color range (from colorless to purple and dark green in 1 and 2, respectively), which are attributed to a substantially reversible photolysis for 1 and dual photolysis and photoinduced secondary ET for 2.
已合成两种有机-无机碘银酸盐杂化物，[(HPBI)·(MeCN)][Ag3I4] (1) 和 [MPBI][Ag3I4] (2)（HPBI⁺ = 1-质子-2-苯基苯并咪唑鎓，MPBI⁺ = 1,3-二甲基-2-苯基苯并咪唑鎓）。它们表现出结构依赖性光致变色，响应速度快且颜色范围广（在1和2中分别从无色变为紫色和深绿色），这归因于1的基本可逆光解以及2的双光解和光诱导二次电子转移。
