Synthesis of naphthalene-fused imidazo[1,2-<i>a</i>]pyridinium salts showing green luminescence with high quantum yields and large Stokes shift
We have synthesized naphthalene-fused imidazo[1,2-<i>a</i>]pyridines by a novel electrophilic iodocyclization of 2-alkynyl-3-arylimidazo[1,2-<i>a</i>]pyridines. Notably, their quaternized salts exhibited green emission with unexpectedly high quantum yields and mega-large Stokes shift and were successfully used for mitochondrial imaging.
