The btp [2,6-bis(1,2,3-triazol-4-yl)pyridine] binding motif: a new versatile terdentate ligand for supramolecular and coordination chemistry

Abstract

Ligands containing the btp [2,6-bis(1,2,3-triazol-4-yl)pyridine] motif have appeared with increasing regularity over the last decade. This class of ligands, formed in a one pot 'click' reaction, has been studied for various purposes, such as for generating d and f metal coordination complexes and supramolecular self-assemblies, and in the formation of dendritic and polymeric networks, etc. This review article introduces btp as a novel and highly versatile terdentate building block with huge potential in inorganic supramolecular chemistry. We will focus on the coordination chemistry of btp ligands with a wide range of metals, and how it compares with other classical pyridyl and polypyridyl based ligands, and then present a selection of applications including use in catalysis, enzyme inhibition, photochemistry, molecular logic and materials, e.g. polymers, dendrimers and gels. The photovoltaic potential of triazolium derivatives of btp and its interactions with anions will also be discussed.

The effect of SO3-Ph-BTBP on stainless steel corrosion in nitric acid

“…The lack of any corrosion enhancement in the presence of SO 3 -Ph-BTBP for both SS304L and SS316L is surprising considering the ligands known affi nity for actinide/lanthanide 3+ oxidation state species [8,10,13] and the previously reported ability of similar BTP derivatives to complex strongly with Fe(II) species [27]. This may in part be due to the requirement for a conformational change in SO 3 -Ph-BTBP from its preferred trans-conformation to the less favoured cis-conformation prior to metal binding [9,11,12], Fig.…”

Influence of Metal, Ligand and Solvent on Supramolecular Polymerizations with Transition‐Metal Compounds: A Theoretical Study

“…24 Pyridine-centered tridentate ligands are highly versatile building blocks that are extensively used in coordination chemistry. 25 For instance, the combination of a tetrazolyl-pyridine (TEP) ligand with Pt(II) led to self-assembled supramolecular nanowires exhibiting aggregation-induced luminecence, as reported by Strassert et al 26 The design of new supramolecular polymers of transition metal complexes with optimal properties for optoelectronic applications requires a fundamental understanding of the mechanism of the self-assembly process. Despite the large number of experimental works dedicated to supramolecular polymers, there have been only a few computational studies, 18,19,[27][28][29] and in particular, there is only one densityfunctional theory (DFT) study involving metal-containing systems.…”

Lanthanide-based self-assemblies of 2,6-pyridyldicarboxamide ligands: Recent advances and applications as next-generation luminescent and magnetic materials

“…[1][2][3][4][5][6][7] Whilst historically this field has been heavily skewed towards transition metal-based systems, there is a smaller sub-section made up of lanthanide-based assemblies that have been the focal point for some research groups owing to their well-known optical and magnetic properties. [8][9][10][11][12][13][14] Moreover, with the current drive to develop more complex luminescent and magnetically interesting materials (e.g.…”
