Microporous polymers with exposed C surfaces have been synthesized by a new pathway of crosslinking fullerenol and terephthaloyl chloride or 1,3,5-benzenetricarbonyl trichloride esterification. The resulting polymers are insoluble solids containing a large ratio of C with hydroxy groups and possess micropores with high specific surface area up to 657 m g. The microporous polymers thus obtained exhibit enhanced hydrogen spillover, which is a unique property of the C surface.
