Abstract

In this study, we designed and synthesized three ligands with 2,2':6',2"-terpyridine (TPY) partially anchored to tetraphenylethylene (TPE)  with the aim of constructing emissive materials. TPE-TPY ligands were assembled with Cd(II) through coordination-driven self-assembly to immobilize fluorophores into metallo-macrocycles, thus leading to emission in both solution and aggregation states Furthermore, Iridium(III) has been incorporated into metallo-macrocycles through hierarchical self-assembly, endowing those supramolecules with more tunable luminescent properties. Those supramolecular metallo-macrocycles were fully characterized by multinuclear NMR (1H and 13C) analysis, 2D NMR spectroscopy (COSY, DOSY and NOESY), ion-mobility mass spectrometry (IM-MS), ultraviolet-visible and fluorescence spectroscopy.
