Synthesis of solid state fluorescent quino[2,3-b]carbazoles via copper(II) triflate-catalyzed heteroannulation: application to detection of TNT

New analogues of solid state fluorescent quino[2,3-b]carbazoles have been synthesized from heteroannulation of quinoline alkynylaldehyde and indole. Their preliminary photophysical properties are studied and application as chemosensory material for detection of trinitrotoluene is explored.
