Synthesis and application of poly-para-phenylene and their derivatives

According to the unique optical,electric,and magnetic properties of poly-para-phenylene and its derivatives as well as their superior toughness and workability of the materials out of them,their preparation methods,properties,and applications were reviewed,the existing problems and research direction were pointed out.The results showed that poly-para-phenylene and their derivatives are the perspective functional polymer materials,which have a broad prospect in their application.However,because of the complexity and diversity of structure and preparation,there are many problems,such as numerous isomers with similar physical properties,being difficult of separation,poor selectivity,low yield,and rigorous conditions of reaction,and so on.
