Abstract

New boron-locked substituted anilido-pyridines were obtained. The compounds exhibit high Stokes shift (up to 147 nm) and practical luminescence quantum yield (up to 62%), both in solution and in a solid state. The compounds demonstrate reversible electrochemical behavior and intrinsic electrofluorochromism. The possibility to modulate the fluorescence by direct electrochemical repetitive on/off switching was demonstrated by the spectroelectrochemical measurements, opening up prospects for creating fluorescent redox-switches based on these compounds.
