A series of 3,5-diaryl-2-heteroarylthiophenes have been synthesized via Fiesselmann type reaction between alkynones and easily available heteroarylmethanethiols or heteroarylmethyl carbamimidothioates. A correlation between compounds structure and efficiency of luminescence has been established. These compounds exhibited photoluminescence with quantum yields up to 83%. An evidence of twisted intramolecular
已经通过炔烃与容易获得的杂芳基甲硫醇或杂芳基甲基氨基甲硫醇盐之间的菲斯曼(Fiesselmann)型反应合成了一系列的3,5-二芳基-2-杂芳基噻吩。已经建立了化合物结构与发光效率之间的相关性。这些化合物显示出光致发光,量子产率高达83%。分子内电荷转移和单线态发射态扭曲的证据已得到证明。
