Three-coordinate organoboron compounds have been demonstrated by a number of research groups to be useful materials in colorimetric/fluorescent sensing and organic light emitting devices (OLEDs). The recent research efforts in our group focus on the systematic investigation of structural and electronic factors that affect the donor-acceptor charge transfer process in three-coordinate boron compounds. In particular, we examined the effect of the presence of a 2nd boron center on luminescent properties and charge transfer properties of the boron compounds and the impact on their performance in fluorescent sensing and OLEDs. Experimental data along with computational results to elucidate the distinct photophysical properties between mononuclear boron and dinuclear boron compounds, linear and non-linear boron compounds will be presented.
