Charge Transfer from Donor to Acceptor in Conjugated Microporous Polymer for Enhanced Photosensitization

A proof-of-concept strategy to trigger charge transfer for improving photosensitization is the covalent modification of conjugated microporous polymers (CMPs) with polycyclic aromatic hydrocarbons (PAHs). Charge transfer from the PAH donor to the Bodipy acceptor in CMPs can facilitate both intersystem crossing and electron–hole separation, leading to excellent performance for both energy- and electron-transfer reactions.
