Abstract

Coumarin-based dye (Z)-N-(7-cyano-9,9,15,15-tetramethyl-9,10,11,13,14,15-hexahydro-6H-benzo[4'',5'']imidazo[1'',2'':1',2']pyrido[3',4':5,6]pyrano[2,3-f]pyrido[3,2,1-ij]quinolin-6-ylidene)pent-4-ynamide (3) was obtained in 81% yield by reaction between primary imine precursor 1 and pent-4-ynoic anhydride (2) under thermal conditions. The title compound was characterized by elemental analysis, melting point, 1H-NMR, 13C-NMR, FT-IR, mass, UV-vis and fluorescence spectroscopy.
