1. A metal-organic framework of the general formula:
M1xM2(2-x)(A), wherein M1 and M2 are each independently different metal cations, A is a combination of a disalicylate organic linker and a modulator different from the disalicylate linker that has a coordinating site, and x is a value from 0.0 to 2.0, wherein the metal-organic framework comprises a localized defect formed by the modulator.
