Multifunctionalization of porous organic polymers (POPs) toward cooperative CO2 catalysis has attracted so much attention in recent years, but it still remains a huge challenge to scientists. In this contribution, concise and efficient method construct aluminum porphyrin-based hyper-cross-linked ionic been demonstrated for the first time, which are featured with high surface areas hierarchical structures. Obviously, preparation metalloporphyrin-based tetraphenylmethane-derived three-dimensional structures is beneficial introduction abundant active sites formation By regulating locations amounts make them highly dispersed easily accessible, catalytic activity as-maded catalyst can be greatly improved cycloaddition conversion cyclic carbonates without cocatalysts solvents, providing highest initial turnover frequency up 8400 h-1 heterogeneous catalysts reported date. addition, recovered by filtration reused at least ten times significant decrease activity. This work not only presents promising strategy improve controlling site proximity via different synthetic methods also offers an attractive perspective field conversion.
