“…Recently, we have presented two series of lanthanide coordination polymers and complexes including organic ligand sensitized 4f‐4f emission of NIR and visible emitters [28] . Despite the wide usage of terpyridine and other tridentate N‐ligands in the coordination chemistry of lanthanides, only a few examples of coordination compounds obtained with scandium have been published, so far: with 4‐amino‐bis(2,6‐(2‐pyridyl))‐1,3,5‐triazine [29] and 2,6‐bis(4‐isopropyl‐4,5‐dihydro‐1,3‐oxazol‐2‐yl)pyridine, [30] which have an N N N coordination site similar to terpyridine, and two with 2,2′:6′,2′′‐terpyridine itself [31,32] . Other examples are in situ generated trivalent scandium complexes with terpyridine or related molecules for catalysis, [33,34] or monitoring the changes of organic‐based luminescence of 2,3,5,6‐tetrakis(2‐pyridyl)pyrazine in presence of Sc 3+ and other metal ions [35,36] .…”
