Abstract: A new isophorone derivative(2-(3-(4-(bis(2-(2-nitrophenoxy)ethyl)amino)styryl)-5,5-dimethylcyclohex-2-en-1-ylidene)malononitrile) of donor-π-acceptor(D-π-A) type which yield was 80.7% was synthesized by Knoevenagel reaction and characterized by FT-IR and 1H NMR. Its UV-Vis absorption spectrum and fluorescent properties, thermal stability and electrochemical properties were preliminarily investigated. The results showed that the target compound had good fluorescence properties and thermal stability and demonstrated instructive explorations for pursuing new luminescent materials.

Key words: D-&, pi, -A molecule, red fluorescent material, optical properties, Knovengel reaction
