3-(iV,ZV-dimethylamino)-2H-1-benzopyran-2-one (DMAC) exhibits a relatively strong shortlived emission (A,, ~460 nm; lifetime, 0.2 ns) in non-polar solvents with a Stokes? shift of about 8000 cm-'. In more polar solvents, the emission shifts, bathochromically (Stokes' shift up to 10 000 cm-' and life
