Aliphatic polyamides containing malonamide group were prepared by condensation reaction of alkylated ethylene diamines and malonyl dichloride. These polymers emitted fairly strong visible lights in a wide range from blue to near yelllow when excited at wavelengths longer than 325 nm, respectively. Also, the fluorescence property was significantly dependent on the pH level, temperature, and solvent polarity. Next, the luminous aliphatic polyester containing a malonate moiety in the main chain was prepared by two-step reaction. The 3 dimensional, fluorescent image patterns of the aliphatic polyester were fabricated by microtransfer molding (μTM).When the patterned film was thermally treated, it exhibited very distinct fluorescence images in a full color range from sky-blue to yellowish green and also to red regions when exited at wavelengths of 325 nm, 488 nm and 580 nm, respectively. |
