Synthesis of fluorescence, aliphatic polyesters and fluorescence image patterning using their photodegradation property |
| 초록 |
Several diols and diacids containing malonate group were polymerized to polyesters of three types through two step condensation reaction. Then they having disordered structures exhibited not only absorption in visible range but also emission of quite strong visible lights in a wide range from blue to near yellow when excited at wavelengths longer than 300 nm despite of aliphatic polyester. These phenomena are due to a certain reaction due to malonate groups, which is contained main chains, through thermaltreatment at high temperature. These shown different photophysical properties according to thermal properties inducing their chemical structures and were decomposed at high temperature. Also their photodegradation of C=C double bond in formed conjugated structures and malonate groups by irradiating strong light was observed. Using these properties, quite visible fluorescence image pattern was formed. |
