Porphyrin based covalent organic frameworks via self-polycondensation for heterogeneous photocatalysis.

A novel porphyrin based covalent organic frameworks (Por-BABN-COF) has been successfully constructed via self-polycondensation of a newly developed AB porphyrin building block possessing two amino groups and two neopentyl acetal at the meso-position. Por-BABN-COF was employed as a heterogeneous photocatalyst for the selective oxidation of sulfides and CO cycloaddition due to its superior light absorption capacity, strong crystallinity and high stability. The high conversion, good selectivity and excellent reusability indicate Por-BABN-COF is a promising photocatalyst for both reactions.
