“…The Ln(III) ions have attracted significant attention because of their unique magnetic and photophysical properties, [134][135][136][137] particularly their ability to provide long-lived characteristic and line-like emission upon sensitisation by coordinated ligands via the 'antenna effect' and consequently in their applications in supramolecular self-assembly chemistry, as our group has demonstrated in series of publications. [16][17][18][19]53,58,[138][139][140][141] Hence they lend themselves to use in other applications such as in biological sensing, OLEDs, and as imaging agents, etc.…”

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.

“…Related with the use of lanthanide complexes in anion signaling two basic mechanism have been reported (i) perturbation, upon anion binding, of the rate of the energy transfer from the antenna to the lanthanide center and (ii) the displacement of water molecules from the coordination sphere of the lanthanide centre by anions, in both cases resulting in changes in the emission intensity of the lanthanide complex. 197,198 The lanthanide heteropentanuclear complexes [Al 3 (Mq) 4 namely negligible changes upon the addition of one equivalent of anion followed by a substantial quenching and a bathochromic shift upon addition of more equivalents.…”

“…The development of novel luminescent probes for intracellular analysis, that are efficient and kinetically stable, is one of the vital goals. Rare earth metal complexes are now versatile targets in many areas of research such as photochemistry, biomedicine and nanotechnology [5][6][7][8][9][10][11][12]. Special attention has been given to the luminescence properties of lanthanide ions emitting at a millisecond lifetime-scale and in the visible region for europium(III) and terbium(III) complexes [13][14][15][16].…”

SummaryNovel phenanthroline derivatives and their europium(III) and zinc(II) complexes have been prepared in up to 92 %. In contrast to the stable zinc complexes, the europium compounds exhibit a strong luminescence in THF solution and complete dissociation of the complexes back to free ligands in DMSO. 1 H NMR studies of the Eu(III)-complexes 5 and 6 also confirmed the existence of different states depending on the solvent used. Moreover, it was found that the compound 5 is stable in EtOH-PBS solutions; here a strong signal in the emission spectra corresponding to the europium ion was detected. These metal complexes can be used as fluorescence markers for the diagnosis of esophageal squamous carcinoma (OE21) cells at low concentrations. Cell images were acquired using the compound 5, 7-9 as luminescent markers. The first images were taken already after 20 min incubation time at a very low concentration range (0.7-1.6 µM).Published as: Sergeeva, N. N.; Donnier-Marechal, M.; Vaz, G.; Davies, A. M.; Senge, M.
