Pluronic-assisted hydrothermal synthesis of microporous polyimides. Application as supports for heterogenized transition metal catalysts

摘要

Porous polyimides were synthesized fast and easily in water by combining the hydrothermal synthesisudwith the use of an amphiphilic block copolymer, Pluronic F-127 (HT-PF method) and were fully characterized.udTheir properties were compared with those of polyimides with the same chemical structureudsynthesized using m-cresol as solvent and isoquinoline as catalyst. Two of the polyimides synthesized byudthe HT-PF method were used as supports to obtain heterogenized palladium or iron catalysts (Pd-(HTPF),udFe-(HT-PF); both metal-polyimides showed good catalytic activity Suzuki CeC coupling reactions andudalkylation of amines with alcohols, respectively without metal leaching detected during the reaction.
