摘要
芳香膦氧基团具有吸电子诱导效应、打断共轭效应、大位阻效应以及多取代位点等特性,在调节分子的光电特性,尤其是选择性优化某一性质,具有独特的优势。因此,芳香膦氧基团非常适于构建综合性能优异的光电功能材料,进而组装高效的有机电致发光器件。近年来,芳香膦氧类材料的合成及应用已经成为有机电致发光领域研究的热点之一,展现出良好的理论研究和商业应用价值。本文综述了近年来芳香膦氧类材料在有机电致发光二极管中的应用研究进展,从该类材料的分子结构设计、热力学性质、光物理性质以及器件性能等方面进行归纳总结,为今后该领域的研究提供借鉴和参考。
Aryl phosphine oxide( APO) groups are excellent precursors in the synthesis of P-containing compounds due to the functional group’s strong electron-withdrawing effect,conjugation interruption effect,steric effect,and multi-position for substitution,which allow modulating the molecular optoelectronic properties,of the designed molecule. Accordingly,APO groups are ideal to construct highly efficient organic light emitting diodes( OLEDs). The molecular design aspects,thermal and photophysical properties for APO based materials and their device performances( such as turn-on voltage,external quantum efficiency,current efficiency and power efficiency) are summarized,using a theoretical approach( current) with practical demonstrate( subsequent submission) to demonstrate the proposed synthesis as practical and flexible in terms of tailored the final OLED.
