Structural and mechanistic studies of excitation- and temperature-tunable multicolor luminescence of triarylborane

Abstract

The development of single-component organic systems with different phosphorescent behaviors remains a formidable challenge. Herein, an organic triarylborane has been synthesized, (3-bromo-2-(phenylethynyl)phenyl)dimesitylborane (1), which can be obtained as racemate (rac-1)...

Substitution position regulating the excitation-dependent fluorescence–phosphorescence emission of formylphenylboronic acids for single-component white light and anticounterfeiting

“…8 So far, only limited success was achieved for single-component small molecule crystals. 5 a ,9 Favereau et al reported that the excitation-dependent fluorescence–phosphorescence (ExDFPh) dual emission of an enantiopure cyclohexane- trans -1,2-bisphthalimide derivative is associated with two different emission origins. The RTP originates from the electron transition of single molecules, while the fluorescence is from the H-aggregates.…”
