Abstract

Abstract Substituents can induce dramatic changes in the photoluminescence properties of N, O-chelated boron complexes. Specifically, the boron complexes of 2-(benzothiazol-2-yl) phenols become bright deep blue-and orange-red-emitting materials depending on amino substituents at the 5-and 4-positions of 2-(benzothiazol-2-yl) phenol, respectively. Absorption and emission data show that the resulting boron complexes have little or small ...
