8‐klmna]acridines are highly luminescent, and all have photoluminescence quantum yields of about 80 %. They show efficient electroluminescence, and can be used as guest molecules with a 4,4′‐bis(N‐carbazolyl)‐1,1′‐biphenyl host in guest/host‐type organic light‐emitting diodes. The best fabricated diodes showed a luminance of about 1900 cd m−12, a luminance efficiency of about 3 cd A−1, and external quantum
通过还原其羰基和随后的修饰,简单修饰苯并[ h ] benz [5,6] [啶子[2,1,9,8 - klmna ] ac啶-8,16 -dione(一种古老且几乎被遗忘的还原染料)O-烷基化可生成溶液处理的紫氮并苯型电活性共轭化合物,适用于有机电子产品。它们的电化学测定电离电势和电子亲和力分别约为5.2和-3.2 eV,基本上与烷氧基取代基的长度无关,并且与DFT计算非常吻合。8,16-二辛基氧基苯并[ h ]苯[5,6] ac啶[2,1,9,8- klmna ] ac啶的晶体结构(FC-8),最有前途的化合物已解决。它在空间群P中结晶,并通过分散力(主要是在叉指的烷基链之间)形成在3D结构中保持在一起的π堆积柱。STM观察到,FC-8分子在沉积在高度取向的热解石墨表面上的单层膜中具有很强的自组织趋势。8,16-二烷氧基苯并[ h ]苯[5,6] ac啶[2,1,9,8- klmna ]
