具有N,C-螯合π共轭骨架的四配位有机硼化合物,其分子内存在的B-N配位作用使分子骨架趋于平面,π共轭性增强,使这类化合物具有较高的电化学和热学稳定性、优异的发光性能和强的电子亲和势,成为非常有发展前景的新型光电材料,已在有机发光二极管(OLEDs)、有机场效应晶体管(OTFTs)、有机太阳能电池、传感等方面进行了广泛研究。在本文中,我们主要介绍了N,C-螯合四配位有机硼化合物的合成方法及其在电子传输材料、发光材料、光致变色材料及有机太阳能电池材料中的应用研究。
Four-coordinated organoboron compounds with a π-conjugated N,C-chelate backbone have high thermal stability, intense luminescence, and strong electron affinity, and thereby, are promising candidates as novel optoelectronic materials for applications in organic light-emitting diodes (OLEDs), organic field-effect transistors (OFETs), organic solar cells and sensors. This article summarized the recent research progress on the synthesis and the application of this important class of optoelectronic materials.
