Abstract

Poly(2,5-dibutoxy-p-phenylenevinylene)s (PDBOPVs) were synthesized by two different methods, namely the organosoluble precursor method followed by thermal treatment, and phase transfer catalysis. Both the organosoluble precursor and PDBOPV were characterized by elemental analysis, IR spectrophotometry, UV-Vis spectrophotometry, gel permeation chromatography, thermal gravimetric analysis and differential scanning calorimetry. Factors affecting the synthesis of PDBOPV via the phase transfer catalysis, such as kind and amount of phase transfer catalyst, kind of solvent, reaction time as well as NaOH concentration were studied. Yield, molecular weight, solubility, conductivity and electroluminescent properties of PDBOPVs were compared. The results showed that the yield and solubility of PDBOPV obtained by phase transfer catalysis are higher than those of PDBOPV obtained by the organosoluble precursor method. However, molecular weight, conductivity and electroluminescence of PDBOPV obtained by the organosoluble precursor method are much higher than those of PDBOPV obtained by the phase transfer catalysis method. Conditions for thermal elimination of the organosoluble precursor to improve the electroluminescent properties were also investigated.

两种不同方法合成聚(2,5-二丁氧基-对苯乙烯)的比较
采用两种不同的方法合成了聚(2,5-二丁氧基-对苯乙烯)s (PDBOPVs),即有机可溶性前驱体法-热处理法和相转移催化法。采用元素分析、红外分光光度法、紫外可见分光光度法、凝胶渗透色谱法、热重分析和差示扫描量热法对有机可溶性前驱体和PDBOPV进行了表征。研究了相转移催化剂的种类和用量、溶剂种类、反应时间以及NaOH浓度等因素对相转移催化合成PDBOPV的影响。比较了PDBOPVs的产率、分子量、溶解度、电导率和电致发光性能。结果表明,相转移催化制得的PDBOPV收率和溶解度均高于有机可溶性前驱体法制得的PDBOPV。然而,有机可溶性前驱体法制备的PDBOPV分子量、电导率和电致发光均远高于相转移催化法制备的PDBOPV。研究了热消除有机可溶性前驱体以改善电致发光性能的条件。
