摘　　要：利用超声辐射法制备可溶性聚{(3-己酰基)吡咯-[2,5-二(对十四烷氧基苯甲烷)]}(PHPDTBA),采用1 H NMR、FT-IR、UV-Vis、XRD、TG和FL等对产物的结构、热稳定性和荧光性能进行表征与分析。UV-Vis显示PHPDTBA在300～500nm范围内有明显的光学吸收。XRD表明PHPDTBA主要以非晶态存在,也存在微小的晶区。PHPDTBA的热失重过程包括己酰基的断裂和十四烷氧基苯基的断裂两个阶段,初始分解温度为195.19℃。PHPDTBA为深蓝色的荧光材料,在CH2Cl2中的荧光量子产率为0.27,stokes位移为77nm。Soluble poly {（3-hexanoyI）pyrrole-[2,5-diyl（p-tetradecoxybenzyhdane）]} （PHPDTBA） was prepareu by ultrasonic irradiation and its structure, thermal stability and fluorescence properties were characterized and analyzed by 1H NMR, FT-IR, UV-Vis, XRD, TG and FL. UV-Vis spectrum showed that PHPDTBA pos- sessed apparent optical absorption at the range of 300-500nm. PHPDTBA existed mainly in amorphous manner while there was a tiny crystalline region according to XRD spectrum. The thermal weight loss process of PHP- DTBA had two phases, the fracture of hexanoyl and p-tetradeeoxybenzyl, with the initial decomposition tem- perature of 195.19℃. PHPDTBA was a sort of deep blue fluorescent material that the stokes displacement was 77nm with a fluorescence quantum yield of 0.27 in CH2Cl2.
