摘要： 合成一种新型含推-拉电子基团的大π共轭高分子聚[(3-辛酰基吡咯-2,5-二)对二甲氨基苯甲烯](POPDMABE).用氢核磁共振谱、傅里叶红外光谱、紫外-可见光谱等分析手段对聚合物POPDMABE进行了结构表征.该聚合物易溶于多种极性有机溶剂和酸性水溶液,易于加工.热重分析表明,POPDMABE可耐180℃的高温.通过X射线衍射和透射电镜研究表明,POPDMABE以晶态和无定形态共存.光致发光光谱表明,在360nm的紫外光激发下,POPDMABE能发出蓝色荧光.

Abstract: A novel water-soluble and π-conjugated polymer, poly[(3-octanoylpyrrole-2,5-diyl)-p-N,N-dimethylaminobenzylidene](POPDMABE) containing strong electro donor-acceptor groups, was synthesized by condensation of 3-octanoylpyrrole with para-dimethylaminobenzaldehyde. The chemical structure of POPDMABE was characterized by 1H NMR, FTIR and UV-Vis spectroscopy. The solubility of POPDMABE in several kinds of solvents was measured. The results show that the POPDMABE can be easily solved in polar solvent and diluted chlorhydric acid. POPDMABE displayed a decrease in mass of about 5% at 210 ℃ in the thermogravimetric apparatus. The crystallinity of POPDMABE was also studied by X-ray diffraction and transmission electron microscope. The results indicate that part of the POPDMABE is in crystal state and the other part is amorphous. The photoluminescence(PL) of POPDMABE was investigated. The result shows that POPDMABE is a good photoluminescence material and blue fluorescence can be observed when the excitation wavelength is 360 nm.
