Abstract

ABSTRACT Eight polythiophene derivatives containing pyrazoline side groups were synthesized by a chemical oxidative coupling polymerization using FeCl3. The crystal structures of four monomers were determined which confirm the almost perpendicular orientation of the thiophene and pyrazoline rings, while the other substituents are more coplanar. Analyses of IR, 1H-NMR, Raman and UV-Vis spectra demonstrated that the suggested polymerization was successful to generate the synthesized polythiophenes with the expected structures. The morphology of the synthesized polythiophenes was studied by SEM. The different substituents attached to the 1- and 3-positions of the pyrazoline side chain led to differences in optical properties, electrical conductivity, and thermal stability of the synthesized polythiophenes. By adding a pyrazoline side chain to polythiophenes, some polymers achieve good solubility, electrical conductivity of about 1.3 × 10–6 S/cm, high fluorescence intensity (above 40,000 a.u.) at 505–550 nm and thermal stability up to 590°C in the air.

含吡唑啉的新型多噻吩衍生物的合成与表征
摘要以三氯化铁为原料,采用化学氧化偶联聚合法合成了8种吡唑啉侧基聚噻吩衍生物。测定了四种单体的晶体结构,证实了噻吩环和吡唑啉环几乎垂直的取向,而其他取代基更共面。IR、1H-NMR、Raman和UV-Vis光谱分析表明,所提出的聚合反应成功地生成了具有预期结构的合成聚噻吩。通过扫描电镜研究了合成的聚噻吩的形貌。吡唑啉侧链的1-和3-位上连接的取代基不同,导致合成的聚硫醇在光学性能、导电性和热稳定性方面存在差异。通过在聚噻吩中添加吡唑啉侧链,一些聚合物获得了良好的溶解性、约1.3×10–6 S/cm的电导率、505–550 nm的高荧光强度(超过40000 a.u.)和在空气中高达590°C的热稳定性。

期刊介绍: Designed Monomers and Polymers ( DMP) publishes prompt peer-reviewed papers and short topical reviews on all areas of macromolecular design and applications. Emphasis is placed on the preparations of new monomers, including characterization and applications. Experiments should be presented in sufficient detail (including specific observations, precautionary notes, use of new materials, techniques, and their possible problems) that they could be reproduced by any researcher wishing to repeat the work. The journal also includes macromolecular design of polymeric materials (such as polymeric biomaterials, biomedical polymers, etc.) with medical applications. DMP provides an interface between organic and polymer chemistries and aims to bridge the gap between monomer synthesis and the design of new polymers. Submssions are invited in the areas including, but not limited to: -macromolecular science, initiators, macroinitiators for macromolecular design -kinetics, mechanism and modelling aspects of polymerization -new methods of synthesis of known monomers -new monomers (must show evidence for polymerization, e.g. polycondensation, sequential combination, oxidative coupling, radiation, plasma polymerization) -functional prepolymers of various architectures such as hyperbranched polymers, telechelic polymers, macromonomers, or dendrimers -new polymeric materials with biomedical applications
