摘　　要：利用芘丁醇和8-壬烯酸的酯化反应,合成了含长链烷基的芘类衍生物8-壬烯酸芘丁酯,用红外光谱(IR)和核磁共振(1H-NMR)表征其分子结构,研究了它在甲苯和硅树脂中的荧光特性和热稳定性,考察了不同芘类衍生物对光学压敏涂料热稳定性的影响。结果表明,合成的含长链烷基的芘类衍生物8-壬烯酸芘丁酯在溶液及涂料中都具有较高的氧猝灭率,随着芘类衍生物链长的增长,荧光分子在溶液及涂料中的氧猝灭率略有减小,而在涂料中的热稳定性有较大的提高。A sort of 4-（1-pyrenny1）-butyl alkyl ester was synthesized by the esterification. The structures were characterized by infrared spectrum （IR） and 1H nuclear magnetic resonance spectrum（^1H-NMR）,and the heat stability was compared of these luminophors in normal and in high temperature. The results show that the long chain of substituted groups on pyrene have a big effect on the oxygen quenching coefficient and heat stability. With the increase of the long chain on pyrene derivatives,there is a little fall of the oxygen quenching coefficient in solution and in paint,but the heat stability has a great advance in paint.
