A new rhodium complex [Rh(cod)(TTT) 2 ] was synthesized by [Rh(cod)Cl] 2 as a precursor, and 4,4',4''-(1,3,5-triazine-2,4,6-triyl)trianiline (TTT) as a ligand. Its structure was verified by 1 H and 13 C NMR. The results indicate that the complex shows high activity in phenylacetylene polymerization. It was applied to the polymerization of phenylacetylene with a yield of 45.0% and Mw = 2.26×10 5 at ultra-low rhodium feed ratio ([Rh.]/[M.]=1/60000).
