Oxidized thiophene incorporated molecules show great potential as luminescent materials. However, most works focused on thiophene-S, S-dioxides (TDO) moiety, rarely on thiophene-S-oxide (TO) incorporated molecules. Herein, TO and TDO incorporated ladder-type molecules, namely IDT2O–H and IDT4O–H, have been designed and synthesized to study their luminescent properties. Compared to IDT4O–H, IDT2O–H
结合有氧化
噻吩的分子显示出巨大的潜力,可作为
发光材料。然而,大多数工作集中在
噻吩-S,S-二氧化物(TDO)部分,很少涉及
噻吩-S-氧化物(TO)结合的分子。在这里,已经设计并合成了TO和TDO掺入的梯形分子IDT2O–H和IDT4O–H,以研究它们的发光特性。与IDT4O–H相比,IDT2O–H不仅在溶液和薄膜状态下显示出更强的红移荧光发射,而且在薄膜状态下还显示出不同寻常的抗Kasha
磷光。实验光谱和理论计算表明,来自其结构的不同能级和轨道特征对于IDT2O–H和IDT4O–H的不同发光特性至关重要。
