Room‐Temperature Phosphorescence and Energy Transfer in Luminescent Multinuclear Platinum(II) Complexes of Branched Alkynyls

“…This, together with the less positive potentials for the oxidation of the polyaromatic alkynes (+ 1.0 to + 1.2 V) [46] relative to that of 1,3,5-(HCCC 6 H 4 CC) 3 C 6 H 3 (approximately + 1.35 V), suggested that the first oxidation waves of complexes 9-14 are probably derived from the ligand-centered oxidation of the polyaromatic alkynyl ligands. The large shift in the potential for the first oxidation of 14 (+ 0.86 V) relative to that of the branched chloroplatinum(ii) complex 1 (+ 1.27 V) is indicative of an oxidation that is predominantly ligand-centered in character.…”

However, an involvement of some metal‐centered character could not be completely ruled out.…”

An Impedimetric Sensor Based on a Gold Electrode Functionalized with a Thiol Self‐Assembled Monolayer Modified by Terpyridine Ligands for the Detection of Free Gadolinium Ions

“…The particular redox and photophysical properties of the metal ions complexes of terpyridine [20][21][22] make them attractive in photochemistry for the design of luminescent devices or as light sensitizers [23]; terpyridine and its derivative can form polymetallic complex species used in electrochemical sensors. In the fields of medicinal chemistry and biochemistry [24][25][26][27][28], functionalized terpyridines are applied to the colorimetric determination of metal ions [29], and to DNA binding agents in cancer diagnos and anti-tumor therapy [30,31]. The affinity of gadolinium(III) for terpyridine is strong [32,33].…”

Crystal structure, luminescence properties and biological studies of a novel polymeric cadmiumII compound: [Cd(Clphtpy)(NCS)(NO3)]n

“…The coordination chemistry of multidentate ␣-terpyridine-based ligands (tpy) is interesting because of their application in emitters for electroluminescence devices and in molecular probes for biochemical research [1][2][3][4][5][6]. Along with the structural features, these ligands and their complexes have interesting electrochemical, catalytic and optical properties [7][8][9].…”
