| Research Abstract |
Carboranes are polyhedral boron cluster compounds containing two carbon atoms in the cluster cage. They have been widely used in various areas. However, there have been few examples on researches on the application in opto-electronic materials. In this study, I have investigated the following topics by using carborane as a key skeleton.
1. Compounds consisting of oligophenyl and carborane were synthesized. It was achieved that high coplanarity as well as deep HOMO/LUMO levels of oligophenyls were provided. 2. Novel conjugated polymers were synthesized, which possessed carborane units in their main chains. The polymer exhibited bright blue emission by photo-excitation. 3. A conjugated unit substituted at the carbons of o-carborane shows aggregation-induced emission, while common emission behaviors are observed, when a conjugated unit is substituted at the B9 (and/or B12) position. Thus, C1,B9,B12-trisubstituted-carborane compounds were prepared, which showed various emissions.
