4,2′:6′,4′′-Terpyridine (4,2′:6′,4′′-tpy) is one of the less well documented isomers of the well-established bis-chelating 2,2′:6′,2′′-terpyridine. The N-donors of the outer rings in 4,2′:6′,4′′-tpy subtend an angle of 120°, leading to a description of 4,2′:6′,4′′-tpy as a divergent ligand. Because it typically binds metal ions through the outer N-donors only, 4,2′:6′,4′′-tpy is an ideal linker for combination with metal nodes (often geometrically flexible d10 ions) in coordination polymers and metallomacrocyclic complexes. The facile functionalization of terpyridines in the 4′-position allows access to a suite of 4′-X-4,2′:6′,4′′-tpy ligands in which the 4′-substituent, X, can be selected to assist in directing the metal–ligand assembly process. This overview of recent advances in the chemistry of 4,2′:6′,4′′-tpy and its 4′-substituted derivatives looks at relationships within a series of chiral polymers, competition between the formation of metallocyclic complexes versus polymers, and the use of extended aryl systems to encourage the formation of coordination polymers in which π-stacking of arene domains dominates in the assembly process. Use of metal(II) acetates is key to the formation of paddle-wheel and larger cluster nodes that direct the assembly of both predetermined and unexpected architectures.

4,2′:6′,4′′-Terpyridines: diverging and diverse building blocks in coordination polymers and metallomacrocycles

A substantially improved methanol yield was achieved from the photoreduction of carbon dioxide under visible light by using a hybrid photocatalyst consisting of molecular cobalt phthalocyanine tetracarboxylic acid (CoPc-COOH) complex immobilized to the organic semiconductor graphitic carbon nitride (g-C3N4) and triethylamine as sacrificial electron donor. The structural and morphological features of the hybrid photocatalyst determined by various techniques like FTIR, UV–Vis, Raman, XPS, TGA, BET etc. After 24 h of light irradiation, the methanol yield by using g-C3N4/CoPc-COOH photocatalyst (50 mg) was found to be 646.5 µmol g−1cat or 12.9 mmol g−1cat with conversion rate 538.75 µmol h−1 g−1cat. However, the use of homogeneous CoPc-COOH (6.5 µmol Co, equivalent to g-C3N4/CoPc-COOH) and g-C3N4 (50 mg) provided 88.5 μmol (1770 μmol g−1cat) and 59.2 μmol (1184 μmol g−1cat) yield of methanol, respectively under identical conditions. The improved photocatalytic efficiency of the hybrid was attributed to the binding ability of CoPc-COOH to CO2 that provided the higher CO2 concentration on the support. Further, the semiconductor support provided better electron mobility and charge separation with the integrated benefit of facile recovery and recycling of the material at the end of the reduction process.
