Abstract

Abstract: Network structures based on Star‐of‐David catenanes with multiple superior functionalities have been so far elusive, although numerous topologically interesting networks are synthesized. Here, a metal–organic framework featuring fused Star‐of‐David catenanes is reported. Two triangular metallacycles with opposite handedness are triply intertwined forming a Star‐of‐David catenane. Each catenane fuses with its six neighbors to generate a porous twofold intercatenated gyroid framework. The compound possesses exceptional stability and exhibits multiple functionalities including highly selective CO2 capture, high proton conductivity, and coexistence of slow magnetic relaxation and long‐range ordering. Abstract : A metal–organic framework, which represents the rare networks composed of Star‐of‐David catenanes, is designed. The structural complexity of the unique framework highlights different facets of the same compound. Remarkably, the material shows highly selective CO2 capture for a molecular‐sieving effect, superionic proton conductivity, and coexistence of slow magnetic relaxation and long‐range ordering.
