By utilizing the coordination unsaturation of 1,2,3-benzenetricarboxylate (1,2,3-BTA) and protonated N,N′-di(3-pyridyl)succinamide (L) in the as-synthesized 1D coordination polymer (CP) of [(H2L)0.5][Zn(1,2,3-BTA)(H2O)]·2H2O (1), we successfully doped an additional half equivalent of Zn2+ and Co2+ ions to yield [Zn3L(1,2,3-BTA)2(H2O)6]·4H2O (2) and [Zn2CoL(1,2,3-BTA)2(H2O)6]·4H2O (2c). Compounds 2 and 2c are also possible through direct one-pot metal–ligand assembly. With the one-pot method, [Zn2.76Co0.24L(1,2,3-BTA)2(H2O)6]·4H2O (2a) and [Zn2.40Co0.60L(1,2,3-BTA)2(H2O)6]·4H2O (2b) are accordingly prepared to demonstrate the universality of hetero-metallic doping and for probing the doping effect on photocurrent responses. Compounds 2, 2a–2c are 2D CPs formed by linking 1,2,3-BTA-based 1D chains through L ligands. Their photocurrent responses were found to be positively related to the Co2+ percentage of the doped materials.
