| 英文摘要 | A series of fluorescent polymers composed of polydimethylsiloxane (PDMS) with a pyrene-terminated side chain were synthesized and characterized. The oxygen quenching of the fluorescence emission and the photophysics behaviors of the pressure sensitive paints (PSP) based on these polymers were investigated. The results showed that the side chain structure of the polymer not only affected significantly the emission intensity, oxygen quenching sensitivity and Stern-Volmer linearity, but also the storage stability of the PSP. The polymers with a longer alkylpyrene side chain terminated by pyrene chromosphere showed higher excimer emission intensity and oxygen quenching sensitivity. Otherwise, the crosslinker for the polymer filming also has some influence on the PSP properties. When tetraethyl orthosilicate (TEOS) was added for the polymer crosslinking, the storage stability of the PSP decreased obviously. But, when polyhydromethylsiloxane (PHMS A) was used, the PSP showed higher oxygen quenching sensitivity and storage stability. All of the data indicated that the pyrene- terminated alkyl side chain structure of the polymers is favorable to the stable aggregation in the condensed state, at the same time, inhibits the aggregation of the pyrene chromospheres, the PSP should have high emission intensity, oxygen quenching sensitivity, Stern-Volmer linearity and storage stability. |
