Polymerized ionic liquid Co-catalysts driving photocatalytic CO₂ transformation.

ABSTRACT: Photocatalytic production of CO from CO₂ has the potential for safe and atom-economic production of feedstock chemicals via in situ carbonylation chemistry. We developed novel ionic liquid-based polymeric materials through radical copolymerisation of 1-butyl-3-vinylimidazolium chloride and photocatalytically active Re- and Ru-complexes that serve as the CO₂ reduction catalyst and photosensitiser, respectively. The crosslinked polymeric framework allows for the facile immobilisation of molecular organometallic complexes for use as heterogenised catalysts; moreover, the involved imidazolium core units co-catalyze the reduction of CO₂ via covalent interaction. The ratio of sensitiser and catalyst was analysed by laser ablation inductively coupled
