首次采用一种新的合成策略，在二溴苯基硼烷存在下，由亚胺基锡烷试剂生成C-C双键，合成了一系列五芳基取代的二氮硼杂环戊烯。平面C（2）N（2）B核4，5位上的芳基取代基对其电子结构有重要影响。所有新的二氮杂硼杂环戊烯在溶液和固体状态下都是发光的。DFT计算表明4，5-C-芳基取代基对LUMO有显著贡献。
A series of pentaaryl-substituted diazaboroles have been prepared for the first time by a novel strategy based on the C-C double bond formation from imidoylstannane reagents in the presence of dibromophenylboranes. The aryl substituents on the 4,5-position of the planar C(2)N(2)B core have substantial effects on their electronic structures. All the new diazaboroles are luminescent both in solution and in the solid state. DFT calculations indicate the 4,5-C-aryl substituents have significant contributions to the LUMOs.
