Expandable applications. a, b) Time course of benzaldehyde and benzyl bromide reductive homocoupling for the synthesis of hydrobenzoin and bibenzyl using gCN−OH and gCN in 1 vol % water–DMF solution. c) Effect of water concentration on photocatalytic coupling reactions. Reaction conditions: 10 mg photocatalysts in 2 mL 1 vol % water‐solvent solution with 8 mM reactant and 40 mM KOH under 410 nm irradiation (30 mW cm⁻²) and 1 bar N₂ at RT. d) Estimated QEs of gCN−OH for different reactions (12 mW cm⁻²). e) Stability of the gCN−OH for the synthesis of bibenzyl.
