Carbazole is a classic tricyclic aromatic compound that has been widely used in organic optoelectronics. Appropriate functionalization on its aromatic rings will significantly increase the possibilities for its application as an optoelectronic material. Position engineering of carbazole not only leads to its structural diversity, but also substantially enriches its functionality. Bicarbazoles have 15 isomers, most of which are well studied and have been applied in organic light‐emitting diodes (OLEDs). However, one isomer, 9,9′‐bicarbazole, is rarely investigated as an OLED material. Therefore, two 9,9′‐bicarbazole derivatives, 3,3′‐di(10H‐phenoxazin‐10‐yl)‐9,9′‐bicarbazole and 3,3′‐di(10H‐phenothiazin‐10‐yl)‐9,9′‐bicarbazole, have been designed and prepared for use as host materials for green and red OLEDs. These two compounds demonstrated good device performances, and it is believed that the 9,9′‐bicarbazole building block could be a novel platform for the design of efficient host materials for OLEDs.

9,9′-联咔唑：有机发光二极管的新分子骨架
咔唑是一种经典的三环芳族化合物，已广泛用于有机光电子学中。在其芳族环上适当的官能化将显着增加其用作光电子材料的可能性。咔唑的位置工程不仅导致其结构多样性，而且大大丰富了其功能。联咔唑有15种异构体，其中大多数已得到充分研究，并已应用于有机发光二极管（OLED）中。然而，很少有人研究一种异构体9,9'-联咔唑作为OLED材料。因此，有两个9,9'-联咔唑衍生物，3,3'-di（10 H -phenoxazin-10-yl）-9,9'-联咔唑和3,3'-di（10 H已设计并制备了吩噻嗪-10基）9,9′-联咔唑，用作绿色和红色OLED的主体材料。这两种化合物显示出良好的器件性能，并且人们认为9,9'-联咔唑构件可能是用于设计OLED高效主体材料的新颖平台。
