Two new derivatives of 4-dicyanomethylene-2,6-dimethyl-4H-pyran were synthesized and characterised. The fluorescence intensity, quantum yield and emission wavelength of these derivatives are reported. Films made from poly(amic acid) with the corresponding chromophore covalently bound show better flu
