英文摘要：

Polyphenylquinoxaline （PPQ） is one of the most important thermoplastic heteroaromatic polymers. The phenyl-substituted quinoxaline ring endows the polymers with high thermal stability, hydrolysis stability, and good solubility in organic solvents. The recent research and development of PPQs has been summarized from the points of monomer synthesis, polymer synthesis, and their applications in high-tech fields. The applications of PPQs as interlayer dielectrics for integrated circuit, electron transporting materials for advanced display device, and proton exchange membranes for fuel cell were emphatically introduced. At last, the future development of PPQs in high-tech areas was prospected.
