摘要
为进一步探究影响分子力致荧光变色性能的因素,合成了 6 种具有不同芳基取代基团的水杨醛亚胺二氟化硼配合物 1-6.结果表明,六种配合物都具有弱的分子内电荷转移过程,除配合物 5 外,其余五种配合物具有聚集诱导发光特性.进一步研究显示,在这一系列的配合物中,配合物 6 具有较好的力致荧光变色性能.量子化学计算结果显示,配合物的力致荧光变色行为受到分子空间效应和偶极矩的影响.
Abstract
To further exploring the factors affecting the molecular machanofluorochromism performance,six salicylaldehydimine diflu-oroboron complexes(1-6)with different aryl substituent groups were synthesized.The results indicated that all complexes exhibited weak intramolecular charge transfer processes,and except for complex 5,the other five complexes displayed aggregation-induced emis-sion properties.Further research showed that complex 6 exhibited well machanofluorochromism performance in this series of complexes.The quantum chemical calculation results illustrated that the machanofluorochromism behaviors of the complexes were influenced by mo-lecular spatial effects and dipole moments.
