1,2,3,5-Tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN)-based porous organic polymers for visible-light-driven organic transformations in water under aerobic oxidation

A series of hyper-crosslinked POPs were constructed by Friedel–Crafts alkylation reaction of 4CzIPN with FDA, which contains a certain quantity of hydrophilic ether residues to facilitate visible-light-promoted aqueous organic transformations.
