近年来,三芳基硼烷在氟离子和氰根离子检测方面的应用受到了越来越广泛的关注.由于具有空的pπ轨道,三芳基硼烷可作为路易斯酸通过路易斯酸-碱相互作用实现对氟离子和氰根离子(路易斯碱)的高选择性检测.硼原子与氟离子或氰根离子的结合破坏了硼中心与芳香取代基的pπ-π共轭,引起三芳基硼烷光物理性质的变化.另外,三芳基硼烷具有优异的发光和载流子传输性质,已被广泛应用于有机电致发光领域,成为一类非常重要的有机光电材料.本文总结了近年来报道的三芳基硼烷的结构特点、构效关系以及在阴离子传感和有机电致发光显示器件中的应用,并在此基础上提出了三芳基硼烷在研究和应用中尚待解决的问题,展望了这类材料的应用前景.
In recent years, the use of triarylboranes for the detection of fluoride and cyanide ions has drawn increasing attention. Due to the empty pπ orbital, triarylboranes are available as Lewis acids via Lewis acid-base interactions Highly selective detection of fluoride ions and cyanide ions (Lewis bases). The combination of boron atoms with fluoride ions or cyanide ions destroys the pπ-π conjugation of boron centers with aromatic substituents, causing the triarylborane photophysics In addition, triarylborane has excellent luminescence and carrier transport properties, has been widely used in the field of organic electroluminescence, become a very important class of organic optoelectronic materials.This paper summarizes the recent reports of triaryl Structural characteristics, structure-activity relationship of borane and its application in anion-sensing and organic electroluminescent display devices. On this basis, the problems that need to be solved in the research and application of triarylborane Application of such materials.
