Water compatibility for heterogeneous photocatalysts has been pursued for energy and environmental applications. However, there exists a trade-off between hydrophilicity and recyclability of the photocatalyst. Herein, we report a conjugated polymer photocatalyst with tertiary amine terminals that reversibly binds CO2 in water, thereby generating switchable hydrophilicity. The CO2-assisted hydrophilicity boosted the photocatalytic efficiency in aqueous medium with minimum dosage. When CO2 was desorbed, the photocatalyst could be simply regenerated from reaction media, facilitating the repeated use of photocatalyst. Hydrophilicity/hydrophobicity control of the polymer photocatalyst was successfully showcased through a variety of organic photoredox reactions under visible-light irradiation in water.

This paper describes the synthesis and characterization of silver, copper and gold complexes supported by several amino-NHC ligands with different amino side arms. The transmetallation process using silver-NHC complexes can be used to prepare amino-NHC copper and gold complexes easily in high yield. In addition, the catalytic activities of copper complexes are examined for arylation of caffeine via C-H bond activation.
