Boron, a group 13 element, has several characteristic structural and electronic features: 1) trivalent boron compounds usually adopt a trigonal planar geometry; 2) due to the presence of a vacant p-orbital, effective orbital interaction with π-conjugated compounds is possible; 3) the presence of a vacant p-orbital is furthermore responsible for high Lewis acidity; 4) the boryl group acts as a π-electron-accepting group particularly in the excited state. The consequent exploitation of these characteristic features of boron in the molecular design enables us to produce sophisticated π-functional materials with attractive photophysical and electronic properties. This account article illustrates our systematic studies on the molecular design and the development of functional π-electron materials using boron as a key element.

Dibenzo[b,g]-fused and dithieno[b,g]-fused BODIPY derivatives were synthesized, and the electronic impacts of the introducing dibenzo- and dithieno-fused structures at both of the b and g bonds in the BODIPY skeleton were investigated. Electrochemical and photophysical measurements demonstrated that these structural modifications effectively enhance the electron accepting ability of the BODIPY skeleton leading to the red-shifted absorption.
