series of T‐ and H‐shaped donor–acceptor (D–A) types of dipyrido[3,2‐a:2′,3′‐c]phenazine (DPPZ)‐based molecules, extended by thienyl and triphenylamino chromophores at the 2,7‐(bottom) and/or 10,13‐positions (top), have been designed and prepared successfully. Synthetic, structural, thermal, spectral, and computational comparisons have been carried out for related compounds because of their adjustable
一系列基于双吡啶[3,2- a:2',3'- c ]吩嗪(DPPZ)的T型和H型供体-受体(D–A)类型,由噻吩基和三苯基氨基发色团在2,7(底部)和/或10,13(顶部)位置已成功设计和准备。由于相关化合物具有可调节的分子内电荷转移特性,因此已对相关化合物进行了合成,结构,热,光谱和计算比较。注意,已经分别获得了一对结构异构体(5和6),其中观察到了明显的UV / Vis和荧光光谱,电化学活性,热稳定性和带隙。此外,化合物6,8,10,11,13,和15表现出优异的热稳定性,和TD 10为它们的值被发现范围从524至646℃,这可以被认为是热稳定的化合物中的有机小分子的最佳基团之一。此外,进行了理论计算,并检查了结构与性质之间的关系,以揭示供体臂的位置和数量对DPPZ受体核的影响。
