Design and emissive features of ionic white-light fluorophore

Illia Serdiuk

Abstract

First ionic white-light emitting fluorophore was designed and target-synthesized and its spectral features were investigated. The design stage included selection of 4'-methoxyflavylium as a prototype blue emitter followed by analysis of thermodynamics of the excited-state intramolecular proton transfer in various 4'-methoxyflavylium derivatives using time-dependent density functional theory calculations. On the basis of such a screening, the best candidate was selected, synthesized, and investigated in various solvents and polymeric films. Pure white light (WL) was attained both in solutions and solid films with fluorescence quantum yields near 20%. This research evidences that WL can be generated with reasonable quantum efficiency by an ionic emitter. The described compound or its derivatives may find applications in white light-emitting electrochemical cells.
