“…82 It is worth noting that due to its relative planarity and strong dipole moment, the 1,2,3-triazole has a physicochemical resemblance to the amide bond, explaining its use as a linker in biological, biochemical and carbohydrate research, 83 as well as interest in 1,2,3-triazole hydrogen bonding behaviour in anion supramolecular chemistry, which has been reviewed by Hua and Flood. 84 Although there have been a number of recent overviews of metal-chelating systems synthesised using the CuAAC reaction, 64,85,86 as a result of the rapid and recent explosion of interest in the terdentate 2,6-bis(1,2,3-trazol-4-yl)pyridine motif (btp), only limited examples of ligands containing this motif have been included. 59,71,87,88 The objective of this review, as stated above, is to address this deficit, detailing the chemistry and the applications of btp ligands which have been reported in the literature over the last few years.…”
