In this work we present new organic glass-forming 2-(3-styryl)-5,5-dimethylcyclohex-2-enylidene)malononitrile fragment containing material IWK capable of forming a thin solid amorphous film from volatile organic solvents (chloroform and DCM). The synthesized glassy material IWK absorption band is between 450 nm to 550 nm. It absorption maximums show small batochromic shift going from less polar to polar solvents. Material IWK is also characterized with intensive photoluminescence, which maximum is dependant on solvent and is between 600 nm to 675 nm. These material properties makes them perspective and would greatly benefit in technological processes constructing electroluminescent devices by laying OLED emission layer with simple “spin-coating” method.
