Abstract

White emission with two sharp strong peaks - a molecular emission peak at 455 nm and an excimer emission peak at 591 nm - was obtained by introducing a terphenyl group into a highly twisted core chromophore, which promoted a molecular orientation in the film state suitable for excimer formation.
