China 3 School of Chemistry, University of Birmingham, Birmingham B15 2TT, UK E-mail: c.ferguson.1@bham.ac.uk Photocatalytic conjugated microporous polymers (CMPs) have provided a platform for using visible light to catalyze a broad range of important reactions. However, certain challenges remain. Firstly, the compatibility of these conjugated materials with green solvents, such as water, remains a significant challenge. Secondly, the diffusion path length for both substrates and light into photocatalytic materials often renders much of the material unusable. Thirdly, mass transfer of a substrate to the material surface limits the photocatalytic rate. Finally, photogenerated holes and electrons often have rapid recombination rates, limiting their performance. In this talk, I will cover a new synthetic route to create photocatalytic mesoporous nanoparticles, introduce ways to increase mass transfer and show how we can elongate radical lifetimes.
