A three-dimensional porphyrin-based porous organic polymer with excellent biomimetic catalytic performance

Abstract

A highly stable porphyrin-based porous organic polymer PPOP-1(Fe) with a three-dimensional diamond structure was synthesized via imine condensation of a tetrahedral aldehyde and a linear porphyrin diamine. PPOP-1(Fe) exhibits excellent catalytic activity as a biomimetic catalyst, because the heme-like porphyrin active centers in PPOP-1(Fe) are exposed toward the open channels, thus accelerating the catalytic oxidation reactions.
