The tridentate dpmp ligand was reacted with Cu-I salt and cyano ligand affording selectively and unexpectedly the polymetallic Cu-11 complex 2 along one-step reaction. The formation of this derivative 2 can be explained by self-assembling processes controlled by adaptive coordination-driven supramolecular chemistry. The solid-state photophysical behavior of 2 was studied suggesting TADF properties.
