Abstract

Metal porphyrins, which possess metal-N coordination centers, are important building blocks for the construction of porous organic materials with catalytic performance. However, most of the previous work has focused on controlling the metal elements instead of the metal-N coordinations. Here, Pt(II) N-confused porphyrin and Pt(II) porphyrin based conjugated microporous polymers were synthesized by Yamamoto coupling reaction. The structural and property differences of Pt-N₃C and Pt-N₄ were studied. Calculations demonstrate that the Pt-N₃C-based porous polymer exhibits broader photoabsorption and narrower bandgap than conventional Pt-N₄-based porous polymers.
