Self-assembled aggregates of 7,10-dibromo-2,3-dicyanopyrazinophenanthrene which act as a new organophotocatalyst in combination with Ni catalyst for the C_aryl–O_acyl cross-coupling reactions of carboxylic acids with aryl halides are described. This visible-light-induced C_aryl–O_acyl bond-formation reaction proceeds smoothly to afford aryl esters with satisfactory to excellent yields.
