Two Ag(I)-imidazolate compounds with distinct chain-like structures, namely, [Ag(dm-bim)]n (1, dm-bim = 5,6-dimethylbenzimidazole) and [Ag(m-bim)]n (2, m-bim = 2-methylbenzimidazole), were synthesized and structurally characterized, respectively. Compound 1 with helical chains exhibited unique luminescence mechanochromism due to short Ag⋯Ag interactions (2.986 Å).
研究人员合成了两种具有独特链状结构的 Ag(I)-imidazolate 化合物,即 [Ag(dm-bim)]n (1,dm-bim =
5,6-二甲基苯并咪唑)和 [Ag(m-bim)]n (2,m-bim =
2-甲基苯并咪唑),并分别对其进行了结构表征。具有螺旋链的化合物 1 由于较短的 Ag⋯Ag 相互作用(2.986 Å)而表现出独特的发光机械变色现象。
