Abstract
The synthesis and characterization of sulfinate addition-responsive turn-on fluorescent molecules are described. Sulfinate addition to diazene-substituted naphthalimide under sulfonyl radical conditions afforded the sulfonyl hydrazides with high quantum yields (up to 0.91 in THF and 0.54 in methanol), which exhibited a large Stokes shift (105 nm) in protic methanol solvent.
