Abstract
Abstract Three novel compounds, trans -2-[ p -( N -ethyl- N -(hydroxyethyl)amino)styryl]- N -methylbenzothiazolium iodide ( 1 ), trans -2-[ p -( N -ethyl- N -(hydroxyethyl)amino)styryl]-1′,3′,3′-trimethylindolium iodide ( 2 ), and trans -2-[ p -( N , N -dimethylamino)styryl]-1′,3′,3′-trimethylindolium iodide ( 3 ), were synthesized and their two-photon induced fluorescence behavior was studied. Under excitation by 1064 nm laser irradiation, the solutions of these compounds exhibit two-photon induced fluorescence with λ max at 639, 666 and 665 nm for 1 , 2 and 3 respectively.
