In this work we present a simply obtainable compound 2-(3-(4-(bis(2-(trityloxy)ethyl)amino)styryl)-5,5-dimethylcyclohex-2-enylidene)malononitrile (IWK) capable of forming a thin solid amorphous film from volatile organic solvents (chloroform and dichloromethane). The synthesized glassy compound IWK absorption band is between 450 nm to 550 nm. It absorption maximums show small batochromic shift going from less polar to polar solvents. Compound IWK is also characterized with intensive photoluminescence, which maximum is dependant on solvent and is between 600 nm to 675 nm. The electron system of molecules were investigated with semi-empirical method ZINDO/S and show, that IWK type molecule chromophore fragment geometrical, electronic, and optical properties are not influenced by N-alkyl substituents.
