Terpyridine-based Self-assembled Heteroleptic Coordination Complexes
Soumyakanta Prusty, Yi‐Tsu Chan
Abstract
Coordination-driven self-assembly of metal ions and organic ligands has been extensively applied over the past few decades, towards construction of various functional two-dimensional (2D) and three-dimensional (3D) architectures. The majority of these structures are homoleptic in nature, consisting of one type of ligand. However, the functionality of self-assembled complexes can be potentially increased by increasing their complexity. To address this, recent efforts have been concentrated on synthesis of heteroleptic complexes composed of more than one type of ligand. This review article highlights the recent developments of 2,2′:6′,2′′-terpyridine (tpy)-based self-assembled heteroleptic coordination complexes. The first part of this review collects examples of heteroleptic tpy complexes constructed in a stepwise manner with metalloligands as primary components, and the one-pot strategies are described in the second part. Coordination-driven self-assembly has been widely used in construction of various functional two- and three-dimensional architectures. The functionality of self-assembled complexes can be potentially increased by increasing their complexity. Hence, the substantial efforts have been devoted to preparing heteroleptic complexes composed of more than one type of ligand. This review article highlights the recent developments of 2,2′:6′,2′′-terpyridine (tpy)-based heteroleptic complexes.
