Porous Macroligands for Heterogenized Molecular (Photo)Catalysis

A fruitful strategy in the design of molecularly-defined heterogeneous catalysts is to immobilize isolated active sites within a hosting framework. The integration of the catalytically active centers into a solid support without loss of performance compared to the homogeneous analog is still a major challenge. To change the paradigm of molecular catalytic processes for fine chemical synthesis and green fuel production, we introduced recently the concept of solid porous macroligand for heterogenized molecular catalysis. Having molecularly-defined active sites, porous macroligands have been found to drive the activity and the selectivity of heterogenized catalytic processes on a similar way as molecular ligands but with the advantage of the structuration in a three-dimensional framework and the confinement within a porous nanospace.

We already demonstrated that fully heterogenous systems based on porous organic polymer macroligand displayed high productivity and stability over the time for the CO₂ to formic acid photoreduction.

This highlights the synthetic versatility of porous macroligands, opening pathways for more sustainable molecular catalytic processes and solar fuel production.

With collaborative advances from both molecular and materials science, breakthrough photosystems using porous macroligands for heterogenized molecular catalysis for efficient carbon-based solar fuel production are likely to emerge in the near future.
