| Research Abstract |
We disclose a new planarized triarylborane in which the tri-coordinated boron atomis embedded in a fully fused polycyclicπ-conjugated skeleton. The compound shows high stability toward oxygen, water, and silica gel, despite the absence of stericprotection around the B atom. Refecting the electron-donating character of theπ-skeleton and the electron-accepting character of the B atom, this compound shows broad absorption bands that cover the entire visible region and a fuorescence in thevisible/near-IR region. In addition, this compound shows dramatic property changes upon formation of a tetra-coordinated borate, such as thermochromic behavior in the presence of pyridine.
