Self-assembly of metal-ion-responsive supramolecular coordination complexes and their photophysical properties

Herein, we describe the synthesis and characterization of two newly self-assembled supramolecular coordination complexes (SCCs) by using the cis-{Pt(PEt3)2}2+ center and two different kinds of pyridyl-derivatized ligands. The photophysical properties of the resulting SCCs in the presence of metal ions revealed that these dipyridyl-containing SCCs hold potential as metal-ion-responsive materials.
