Many fluorophores, and all bright light-emitting substrates for firefly luciferase, contain hydroxyl or amine electron donors. Sulfonamides were found to be capable of serving as replacements for these canonical groups. Unlike "caged" carboxamides, sulfonamide donors enable bioluminescence, and sulfonamidyl luciferins, coumarins, rhodols, and rhodamines are fluorescent in water.
