Electron-withdrawing heterocyclic units are found in most organic optoelectronic materials. Benzo[1,2-d:4,5-d′]bis([1,2,3]thiadiazole) is an interesting new heterocyclic system, the chemical properties of which are much less studied than other fused thiadiazoles. Cyano derivatives of electron-accepting heterocycles are known as potential components of photoluminescent materials. In this communication, benzo[1,2-d:4,5-d′]bis([1,2,3]thiadiazole)-4-carbonitrile was successfully obtained via the cyanation of 4-bromobenzo[1,2-d:4,5-d′]bis([1,2,3]thiadiazole) with copper(I) cyanide in DMF. The structure of the newly synthesized compound was established by means of elemental analysis, high-resolution mass spectrometry, 1H and 13C NMR, and IR spectroscopy.

苯并[1,2-d:4,5-d′]双([1,2,3]噻二唑)-4-甲腈

大多数有机光电材料中都含有吸电子杂环单元。苯并[1,2-d:4,5-d′]双([1,2,3]噻二唑)是一种有趣的新型杂环体系，与其他稠合噻二唑相比，其化学性质的研究要少得多。受电子杂环的氰基衍生物被认为是光致发光材料的潜在组分。在本通讯中，通过4-溴苯并[1,2-d]的氰化成功获得苯并[1,2-d:4,5-d']双([1,2,3]噻二唑)-4-甲腈:4,5-d']双([1,2,3]噻二唑)与氰化铜(I)在DMF中的反应。通过元素分析、高分辨率质谱、1H和13C NMR以及红外光谱确定了新合成化合物的结构。
