Abstract

The reaction of lithium amide LiN(Si(Me)₃)₂ and ditopic heterocyclic ligand benzo[1,2-d:4,5-d′]bis(thiazole)-2,6(3H,7H)-dithione (H₂L) in dimethoxyethane (DME) affords the binuclear molecular complex Li₂L(DME)₄ (I). New compounds [Li₂L(DMSO)₄·(DMSO)₂]_n (II) and [Li₂L(DMSO)₄·(THF)₂]_n (III) are prepared by the recrystallization of compound I using a DMSO–diethyl ether or DMSO/THF mixture of solvents, respectively. According to the XRD data, these compounds are one-dimensional Coordination polymer (CPs) differed by the arrangement of the bis(thiazole) fragments relative to each other and the Li₂O₂ fragment in the polymer chain, which affects the luminescence properties. The molecular structures of compounds I–III are determined by XRD (CIF files CCDC nos. 2334192 (I), 2334193 (II), and 2334194 (III)).

异位中心对称巯基苯并噻唑二锂盐：从分子络合物到发光一维配位聚合物

锂酰胺LiN(Si(Me)3)2与双异位杂环配体苯并[1,2-d:4,5-d ']双（噻唑）-2,6(3H,7H)-二硫酮（H2L）在二甲氧基乙烷（DME）中反应得到双核分子络合物Li2L(DME)4 (I)。用DMSO -二乙醚或DMSO/THF混合溶剂将化合物I重结晶，分别制备了新的化合物[Li2L(DMSO)4·（DMSO）2]n （II）和[Li2L(DMSO)4·（THF）2]n （III）。根据XRD数据，这些化合物是一维配位聚合物（CPs），其结构不同于双（噻唑）片段的相对排列和聚合物链上Li2O2片段的排列，这影响了它们的发光性能。化合物I - III的分子结构由XRD测定(CIF文件CCDC编号2334192 （I), 2334193 （II）和2334194 (III)）。
