“…Another important feature is the strong dependence of the fluorescence emission properties of the metal complexes, especially the zinc(II) ones, on environmental factors such as the nature and polarity of the solvent. A straightforward application could be the use of such com- plexes in devices for the detection of volatile organic compounds [51]. Moreover, the fluorescence quenching that prevails in complexes of closed-shell metal ions in polar solvents or empty-shell metals, such as transition metal ions, corresponds to the 'OFF' situation, while the 'ON' signal is set by the intense fluorescence emission from the free ligand.…”

“…The zinc complexes of pyridine derivatives have received considerable attention recently because of their potential application in electroluminescent displays and fluorescent sensors [10][11][12][13]. Some zinc(II) complexes exhibit photoluminescence with high quantum efficiency and can be used as blue emitting materials especially, however they are still scarce relative to other metal complexes [14][15][16][17][18][19][20].…”

Three bidentate ligands, 4-phenyl-2-(2-pyridyl)-quinoline (ppq), 6-(carbazol-9-yl)-4-phenyl-2-(2-pyridyl)-quinoline (cpq) and 6-diphenylamino-4-phenyl-2-(2-pyridyl)-quinoline (dpq) and their zinc(II) complexes, have been designed and synthesized. The crystal structure of [Zn(ppq) 2 Cl]PF 6 shows that the central zinc atom is coordinated with one chloride and four nitrogen atoms from two ligands. The introduction of an electron-donating substituent such as carbazole or an aromatic amine group at the 6-position of the quinoline moiety can generate colored tunable Zn complexes, and the photoluminescence (PL) wavelength was modulated from 418 nm for [Zn(ppq) 2 Cl]PF 6 to 591 nm for [Zn(cpq) 2 Cl]PF 6 and 638 nm for [Zn(dpq) 2 Cl]PF 6 in CH 2 Cl 2 solution. The electroluminescence spectrum of [Zn(dpq) 2 Cl]PF 6 exhibits pure red light emission with the Commission Internationale de L'Eclairage (CIE) coordinates (0.63, 0.36) and a maximum at 648 nm.

“…Because 2,2 0 -dipyridylamine, its derivatives and metal complexes have exhibited excellent luminescent properties [9], which can be used not only as efficient blue emitters in electroluminescent devices but also as chemical sensors for specific organic molecules [10]. Herein, we report two new coordination polymers, [Cd 2 (tppda)(DMF) 2 (l-SCN) 2 (SCN) 2 ] n (1), and [Cd 2 (tppda)(l-SCN) 4 ] n (2), based on a bent ligand tppda (Scheme 1).…”
