摘要：
Dichromate capture: A 3D cationic metal-organic framework consisting of distorted octahedral and tetrahedral cages was constructed by using Ag I and 4,4′-bis(1,2,4-triazole). The complex exhibits fast exchange, high trapping capacity, and good selectivity for Cr2O 72- through single-crystal to single-crystal transformation. The complex also features a bluish violet luminescence that is distinctly quenched after Cr2O72- exchange. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
