Abstract

Wholly aromatic polyketones with 2,2′-dimethoxy-1,1′- binaphthyl-6,6′-diyl units in the main chains were synthesized through Suzuki-Miyaura coupling polymerization catalyzed by nanosized palladium clusters, which were easily prepared from Pd(OAc)₂, PPh₃, K₂CO₃, and Bu₄NOAc in 1,4-dioxane. The resulting polyketones have both high thermal stability (high T_g) and solubility in common organic solvents, such as CHCl₃ and N,N-dimethylformamide (DMF). Flexible and pale brown films were obtained by casting from a CHCl₃ solution.
