| Outline of Final Research Achievements |
Among various main-group elements, boron is particularly a useful element to create pi-conjugated skeletons with unusual electronic structures. In this study, we developed various types of optoelectronic functional molecules by pursuing the characteristic features of boron. So far, we have shown that the triarylborane skeleton can be stabilized without steric protection by constraining the structure in a planar fashion. By taking this design strategy one-step further, we developed near-infrared fluorescent materials and luminescent stable organic radicals. We also in-depth studied the complex formation between the planarized boron-containing π-electron systems and Lewis bases in both ground and excited states, and achieved controlling over the supramolecular polymerization processes. Furthermore, we applied the boron π-electron systems to organic electroluminescent devices and fluorescence imaging to demonstrate their potential utilities in these aspects.
