摘　　要：兼具高效发光和电荷传输特性的有机半导体是实现有机电泵浦激光的理想候选材料,但其分子设计与合成面临着巨大挑战。高载流子传输和高效固态发光效率之间存在着天然的矛盾,这是因为高载流子传输要求分子紧密堆积并具有强的分子间相互作用,但这种相互作用会显著降低固态发光效率。本文综述了近年来报道的兼具电荷传输特性和高发光效率的联苯衍生物的研究进展,重点介绍了约20余种基于联苯衍生物的有机半导体材料,包括分子的设计策略、相关的光电性能及其在光电器件方面的应用,为兼具高电荷传输特性和高发光效率的有机半导体材料的研究提供了指导和借鉴,同时为发展与实现有机电泵浦激光奠定了材料基础。本文还对该领域未来发展的挑战、方向及机遇进行了简单评述。Significance Organic semiconductors,which combine high-efficiency light-emission and charge-transport properties,are ideal candidates for realizing organic electrically pumped lasers.However,there are still many challenges in the design and synthesis of materials with such properties.This is because of the intrinsic contradiction between high carrier transport and efficient solid-state emission efficiency in organic solids.High carrier transport requires intense molecular packing and strong intermolecular interactions;however,such interactions can significantly reduce solid-state luminescence efficiency.This review summarizes the recent research advances of biphenyl derivatives with charge transport properties and high luminescence efficiency.Approximately 20 biphenyl derivatives are introduced,including molecular design strategies and related optoelectronic properties and their application in optoelectronic devices.This review on organic conductive materials based on biphenyl derivatives with high luminous efficiency provides meaningful guidance and a material foundation for the development of organic electrically pumped lasers.This paper also briefly reviews challenges,development directions,and opportunities for the future development of the field.Progress Organic electroluminescence is a process of directly converting electrical energy into light.It occurs in organic materials where they emit light under the action of an applied electric field or current.Organic electroluminescent devices are mainly divided into two categories:organic light-emitting diodes(OLEDs)and organic light-emitting transistors(OLETs).In 1963,Pope et al.reported the preparation of the first OLED using anthracene single crystals;however,electroluminescence was only observed in anthracene single crystals with a thicknesses of 10-20μm when the driving voltage was as high as 400 V.The construction of high-performance devices requires light-emitting materials with high mobility.In numerous literature reports,we have found that biphenyl deri
