- W1024283670 abstract "A vizben oldodo 5,10,15,20-tetrakisz(paraszulfonato-fenil)porfirin (H2P4-) sikon kivuli (OOP: out-of-plane) femkoplexeinek kepződest vizsgaltuk Tl(III) es Hg(II) ionokkal. Azonositottuk es jellemeztuk a TlP3-, HgP4-, Hg2P28-, and Hg3P26- komplexeket spektralis, fotofizikai es fotokemiai sajatsagaik alapjan. Ket [Ru(LL)(CN)4]2- tipusu komplex sorozatot szintetizaltunk (LL=2,2’-bipiridin (bpy), 1,10-fenantrolin (phen), szubsztitualt es deuteralt szarmazekaik) es jellemeztunk UV-Vis, IR, Raman spektroszkopiaval, fotofizikai es fotokemiai sajatsagaik alapjan. Meghataroztuk a [Ru(dcb)(CN)4]4- es [Ru(dpp)(CN)4]2- protonalodasi allandoit (dcb=4,4’dikarboxi-bpy es dpp=2,3-bis-2-piridil-pyrazin). Elmeleti szamitasokat vegeztunk a [Ru(bpy)2(CN)2] es [Ru(LL)(CN)4]2- komplexekre (LL= -CH3, -C6H5 es COO- csoportokkal szimmetrikusan 4,4’ szubsztitualt bpy)). A [Ru(x,x’-dmb)(CN)4]2- (ahol x=3,4,5,6 es dmb=dimetil-bpy) komplexekre elmeleti szamitasokkal kapott jellemző szerkezeti, fotofizikai es fotokemiai sajatsagokat kiserleti eredmenyekkel igazoltuk. Uj ketcentrumu Ru(II)-alapu komplexek prototipusat a [(bpy)2Ru(µ-bppz)Ru(CN)4] komplexet es metilalt szarmazekat a allitottuk elő es jellemeztuk kulonboző spektroszkopiai modszerekkel (UV-Vis elnyelesi es lumineszcencia, IR, NMR) modszerekkel. A komplexek ket-ket izomeret azonositottuk NMR spektroszkopiai valamint az elmeleti szamitasok eredmenyeinek osszevetesevel. | Formation of out-of-plane (OOP) metalloporphyrins of thallium(III) and mercury(II) with water soluble 5,10,15,20-tetrakis(parasulfonato-phenyl)porphyrin (H2P4-) was investigated. Spectral, photophysical and photochemical characteristics of TlP3-, HgP4-, Hg2P28-, and Hg3P26- complexes have been determined. Two series of [Ru(LL)(CN)4]2- complexes have been synthesized (LL=2,2’-bipyridine (bpy), 1,10-phenanthroline, and their substituted derivatives and several deuteriated isotopologues) and characterized by UV-Vis, IR, Raman, NMR spectroscopy, and photophysical and photochemical properties were measured. Stepwise protonation constants of [Ru(dcb)(CN)4]4- and [Ru(dpp)(CN)4]2- have been determined (dcb=4,4’dicarboxy-bpy, bpp=2,3-bis(2-pyridyl)-pyrazine). Theoretical calculations have been performed on [Ru(bpy)2(CN)2] and [Ru(LL)(CN)4]2- complexes (where LL is 4,4’ disubstituted bpy with -CH3, -C6H5 and COO- groups). All significant structural, photophysical and photochemical properties of [Ru(x,x’-dmb)(CN)4]2- (where x=3,4,5,6 and dmb=dimethyl-bpy) predicted by the theoretical calculations have been supported by the experiments. The [(bpy)2Ru(µ-bppz)Ru(CN)4] complex as prototype of new dinuclear Ru(II)-based complexes and its methylated derivative have been synthesized and characterized by various adequate spectroscopic (UV-Vis absorption and emission, IR, NMR) methods. Two isomers of the complexes have been assigned by NMR spectroscopy and theoretical calculations." @default.
