abstract A family of hemisalen fluoroborate complexes has been prepared and characterized. These new fluorophores exhibit an intense blue emission upon irradiation with UV light. Interestingly, the introduction of bulky aromatic substituents enhanced the quantum yield considerably, up to 44%. Upon studying various solvents, it appeared that the effect of the phenyl substituents is more of electron donating nature than of restricting the intramolecular motion of the dyes.
