Two new derivatives of 4-dicyanomethylene-2,6-dimethyl-4H-pyran and the corresponding poly (amic acid) were synthesized and characterized. The poly (amic acid) exhibited good solubility in common organic solvents. Fluorescence intensity, quantum yield, and emission wavelength for these chromophore derivatives are reported. The films made from poly (amic acid) covelently bounded with corresponding chromophore show better fluorescence effects than that of corresponding chromophore monomers.

Key words: PYRANE P, FLUORESCENCE INTENSITY, POLYAMIC ACID
