Strong and insusceptible photo-emissions from an intramolecular weak hydrogen bond strengthened twisted fluorophore

Abstract

Intramolecular weak hydrogen bonds of CH⋯O and CH/Pi were introduced into a twisted fluorophore backbone of 1,4-bis(2,2-diphenylvinyl)benzene, which enables the fluorophore to emit violently and stably in both solubilized and aggregated states, and be inert to solvent environments and preserve over 10% quantum yield at temperature as high as 90 °C in solution.
