In this work, chalcogen functionalized dithiophenes, equipped on both extremities with chalcogen-bonding recognition heterocycles, have been prepared following two synthetic pathways. The insertion of the chalcogenazolo[5,4-β]pyridine allows the control of the organization at the solid state. X-Ray diffraction analysis of the single crystals, showed that the Te-doped derivatives give the most persistant assemblies, with the molecules arranging at solid-state in wire-like polymeric structures through Te⋯N interactions. As expected, the introduction of the Se and Te atoms, dramatically decreases the emission properties, with the Te-bearing congeners being virtually non emissive.

通过硫族元素键的联苯噻吩的非共价桥联

在这项工作中，已按照两个合成途径制备了硫属元素官能化的二噻吩，在两个末端均配备了硫属元素键识别杂环。硫属元素氮并[5，4-β]吡啶的插入允许在固态控制组织。单晶的X射线衍射分析表明，掺Te的衍生物能提供最持久的组装，分子通过Te⋯N相互作用以固态排列在线状聚合物结构中。不出所料，Se和Te原子的引入大大降低了发射性能，而含Te的同类元素实际上是不发光的。
