　　Exploration of new synthetic strategies for constructing functional macromolecules with well-defined structures is of critical importance in polymer science.Our research group has been dedicated to the development of new polymerization routes from alkyne reactions,and has succeeded in the synthesis of a large variety of new functional polymers from alkyne monomer.Recently,we have developed a series of three-component alkyne polymerization reactions,including catalyst-free polycoupling of alkynes,aldehydes and boron trichlorides,indium or copper-catalyzed polymerization of alkyne,aldehyde and amines,copper-mediated polycoupling of alkynes,aldehydes and amino acids,palladium-catalyzed polymerization of alkynes,aroyl chlorides and either thiols or amines.Through the polymerization reactions,a number of tailor-made macromolecules with precise structures have been synthesized.The resulting polymers show unique properties such as optical nonlinearity,light refractivity,photopatternability,magnetism,chiroptical activity,and aggregation-induced emission characteristics,which make them promising candidates for high-tech applications.
