摘　　要：利用邻-碳硼烷骨架中可变的C-C键,将在聚集态会发生猝灭(ACQ)的传统发光分子和具有振动自由度的碳硼烷基团连接起来,合成了带有聚集诱导发光(AIE)效应的邻-碳硼烷基发光分子。通过紫外可见吸收光谱、DFT计算、发射光谱及晶体结构测定等手段,研究了邻-碳硼烷可变的C-C键对化合物性质的影响。结果表明,在邻-碳硼烷骨架的碳原子上引入不同的取代基可以改变C-C键的振动特性,从而能够调控化合物的发光性质,并有效实现从ACQ到AIE的转变。The variable C-C bond of o-carborane cage was treated as a vibrational factor. A temptation to synthesize AIE-active o-carborane luminophores were carried out via coupling o-carborane with conventional luminophores who suffered from ACQ（aggregation-caused quenching） effect. Meanwhile, the photophysical properties were investigated by UV-Vis spectra, DFT calculations, PL spectra and crystal structure analysis. The results indicate that different substituents（H, ethyl and phenyl） in o-carboranes could remarkably affect its vibration performance.Ultimately, photophysical properties can be tuned from ACQ to AIE.
