Diversity of supramolecular assemblies based on photoactive Cu(I) trimetallic building blocks and N donor ditopic ligands: from 1D coordination polymers to metallacycles

A series of polymetallic Cu(I) assemblies C1-4 was selectively obtained by self-assembly of a preorganized trimetallic precursor B with 3,3'-bipyridine ligand L1 and structurally related longer ligands L2-4, respectively, allowing...
