首先利用超声辐射法制备聚{（3-丁酰基）吡咯-[2，5-二（对十四烷氧基苯甲烷）]}（PBPDTBA），然后将PBPDTBA腮化制备聚}（3-丁酰基）吡咯-[2，5-二（对十四烷氧基苯甲烯）]}（PBPDTBE），采用红外光谱、紫外可见吸收光谱、热失重曲线和荧光光谱等对产物的结构和性能进行表征与分析。结果表明，PBPDTBE易溶于多种有机溶剂，在氟仿中的溶解度为0．66g／mL；PBPDTBE氯仿溶液和薄膜在400nm～600nm具有显著的光学吸收，共轭吸收峰分别位于455nm和462nm；PBPDTBA和PBPDTBE的热分解过程分为两个阶段，分别对应丁酰基和对十四烷氧基莱基的分解，初始分解温度分别为210．45℃和230．01℃。PBPDTBA和PBPDTBE均为绿色发光材料，最大发射波长分别为514nm和520nm。
Poly I (3-butyryl) pyrrole-[- 2, 5-diyl (p-tetradecoxybenzylidane) ]} (PBPDTBA) was synthesized by ultrasonic irradiation method, and then poly ] ( 3- butyryl) pyrrole-[ 2, 5-diyl ( p- tetradecoxybenzylidene )]} (PBPDTBE) was prepared by reaction of PBPDTBA with chloranil. Their molecular structures and properties were characterized by FT-IR spectra, UV-Vis spectra, TG and PL spectra. The result show that PBPDTBE exhibits good solubility in organic solvents and the solubility in chloroform is 0.66 g/mL. The optical absorption of PBPDTBE in CHC13 solution and PBPDTBE film is broad in the wavelength range of 400 nm-600 nm and the absorption peaks are located around 455 nm and 462 nm, respectively. Thermal decomposition processes of PBPDTBA and PBPDTBE are divided into two steps, which correspond to the fracture of butyryl group and tetradecoxyphenyl group respectively, and the initial decomposition temperature is 210,45℃ and 230.01℃ , respectively. PBPI)TBA and PBPDTBE are both green light-emitting materials, and the maximum emission wavelengths are located at 514 nm and 520 nm, respectively.
