摘要/Abstract

摘要： 以偶氮苯为主链的共轭聚合物可以用常见的原料——间苯二胺、对苯二胺、邻苯二胺和邻氨基苯酚通过重氮化及耦合来合成。不同合成条件获得的产物差别很大,如在亚硝酸钠与原料比例不同的情况下,产物的溶解性和导电性有很大差异。通过对合成的聚合物掺杂碘,研究其导电性,得出控制适量的亚硝酸钠比例和掺杂比例可以提高聚合物的导电性。4种不同原料获得的聚合物中,以邻苯二胺和邻氨基苯酚为基础的聚合物更值得进一步研究,将其由半固体状态进一步固化将使其更有应用前景。这种新型共轭材料成本低廉、合成简单,在光电和光伏器件中将得到广泛应用。

Abstract: The conjugated polymer with an azobenzene backbone can be synthesized by diazotization and coupling using m-phenylenediamine, p-phenylenediamine, o-phenylenediamine and o-aminophenol. The products obtained by different synthesis conditions are very different. For example, the solubility and the conductivity of the products are very different when different amout of NaNO₂ are used. The conductivity of synthetic polymers were studied after doping and the results show that the conductivity of synthetic polymers can be improved by controlling the doping ratio of NaNO₂. As the result, poly (azo-o-phenylenediamine), and poly(azo-o-aminophenol) are relatively more worthy of further study among the four different types of polymers, because they are of semi-solid state and the future research will be focused on their solidification. The novel material will be cheaper and gain more applications.

Key words: poly (azobenzene), synthesis, purification, conductivity, computer simulation
