Spaced Double Hydrogen Bonding in an Imidazole Poly Ionic Liquid Composite for Highly Efficient and Selective Photocatalytic Air Reductive HO Synthesis.

Photocatalytic oxygen reductive HO production is a promising approach to alternative industrial anthraquinone processes while suffering from the requirement of pure O feedstock for practical application. Herein, we report a spaced double hydrogen bond (IC-H-bond) through multi-component Radziszewski reaction in an imidazole poly-ionic-liquid composite (SI-PIL-TiO) and levofloxacin hydrochloride (LEV) electron donor for highly efficient and selective photocatalytic air reductive HO production. It is found that the IC-H-bond formed by spaced imino (-NH-) group of SI-PIL-TiO and carbonyl (-C=O) group of LEV can switch the imidazole active sites characteristic from a covered state to a fully exposed one to shield the strong adsorption of electron donor and N in the air, and propel an intenser positive potential and more efficient orbitals binding patterns of SI-PIL-TiO surface to establish competitive active sites for selectivity O chemisorption.
