Abstract

A B-phenyldibenzo[b,f]borepin planarized with two methylene bridges was synthesized. The structural constraint on the B-phenyl group resulted in a bathochromic shift of the absorption and fluorescence properties as well as enhanced Lewis acidity. A donor-π-acceptor type derivative based on this scaffold exhibited intense fluorescence irrespective of the solvent polarity.
