Two Sn(iv)porphyrin-based supramolecular squares were synthesized, showing efficient photocatalytic degradation of Eriochrome Black T dye, with one of them having a higher pseudo-first-order degradation rate constant.
Two Sn(iv)porphyrin-based supramolecular squares (1 and 2) were synthesized via the reaction of Re(CO)(5)Cl with two [trans-bis(4-pyridyl)(porphyrinato)]Sn(iv) complexes (SnP1 and SnP2). Although the structural framework of these architectures was fixed with a closed 2D tetrameric array, altering the substituent on the Sn(iv)porphyrin units not only produced conformationally different forms but also led to distinctly different nanostructures. These nanostructured materials efficiently performed photocatalytic degradation of Eriochrome Black T (EBT) dye, thereby exhibiting degradation efficiencies between 88 and 95% within 90 min in aqueous media under the irradiation of visible-light. It was also found that the pseudo-first-order degradation rate constant of 2 was higher than that of 1.
