Self‐Sorting of Metal–Organic Polymeric Assemblies in Gels: Selective Templation and Catalysis of Homodimers

The development of generic strategy is essential for the construction of higher order supramolecular assemblies from the mixture of molecular components. Such higher order aggregations are possible through a self-sorting phenomenon, which is not well-explored in gel materials. Here, first examples of self-sorting in the coordination polymer (CP) based gels have been explored using three and four component systems. The self-sorting phenomenon has been monitored through a [2+2] photochemical reaction in the gel state and characterized by 1 H NMR, diffuse reflectance spectroscopy (DRS) and single crystal XRD analyses. Furthermore, AgI was shown to act as a supramolecular catalyst for the [2+2] photochemical reaction in gels.
