Abstract The effect of chemical substances is reported on the structure, surface morphology, and material properties vanadium oxide thin films. study concentrated effects initial materials (e.g., NH 4 VO 3 , NaVO 2 vanadyl acetylacetonate, ammonium decavanadate) various additives acids, chelate ligand, reduction reagent, tensides). syntheses are based sol-gel chemistry. important aim technique ...

White organic light emitting devices were fabricated using phosphorescent materials. The device structure was ITO/ NPB (20 nm/ DPVBi(x nm)/CDBP:5% Ir(btp)2acac(35 nm)/Alq3(y nm)/BCP(5 nm)/CsF(1 nm)/Al (150 nm), where NPB is a N,N'-bis-(1naphthyl)-N,N'–biphenyl-1,1'-biphenyl-4,4'-diamine as a hole transporting layer, DPVBi is 4,4 '-bis(2,2 -diphenylvinyl)-1,1 '-biphenyl as blue fluorescent dye, ...

In the title mononuclear complex, [Pt(CH(3))Cl(C(45)H(41)N(3)P(2))], the pyridine-2,6-diamine ligand can be viewed as a centrosymmetric motif having two pendant N-benzyl-N-[(diphenyl-phosphan-yl)meth-yl] arms, the two P atoms of which chelate to the Pt(II) ion, forming a ten-membered metallocycle. A distorted square-planar coordination geometry around the Pt(II) atom is completed by a methyl li...

A new complex [Dy(C5H7O2)3(C5H5NO)]2·2CHCl3 (1) has been synthesized by the reaction of pyridine-N-oxide with dysprosium (III) acetylacetonate in an n-heptane/chloroform mixture (1/20). X-ray data show that each atom is chelate-like coordinated three ligands and oxygen from two bridging molecules pyridine-N-oxide, which unite atoms into a binuclear complex. Static (constant current) dynamic (al...

Although paraCEST is a method with immense scope for generating image contrast in MRI, it suffers from the serious drawback of high detection limits. For a typical discrete paraCEST agent the detection limit is roughly an order of magnitude higher than that of a clinically used relaxation agent. One solution to this problem may be the incorporation of a large payload of paraCEST agents into a s...

Several new cobalt(III) complexes containing (3-aminopropyl)dimethylphosphine (pdmp) have been prepared, and their molecular structures have been determined. A dichloro complex of trans(Cl,Cl)-cis(P,P)-[CoCl(2)(pdmp)(2)]PF(6) (1) was prepared from trans-[CoCl(2)(py)(4)]Cl.6H(2)O and pdmp. X-Ray crystallography confirmed the (C(2))-chair(2) conformation of two six-membered pdmp chelate rings in ...

In the title complex, [Ni(C(7)H(4)NO(3)S)(2)(C(3)H(10)N(2))(2)] or [Ni(sac)(2)(pen)(2)] (sac = saccharinate or 1,1,3-trioxo-2,3-dihydro-1λ(6,2)-benzothia-zol-2-ide and pen = propane-1,3-diamine), the Ni(II) ion sits on an inversion center, being coordinated by two N atoms of the sac ligands, which occupy trans positions, and four N atoms of the bidentate pen ligands to define a distorted octa-h...

In the title compound, [CrCl(2)(C(3)H(10)N(2))(2)]ClO(4), the Cr(III) atom is coordinated equatorially by four N atoms of two propane-1,3-diamine (tn) ligands and axially by two mutually trans Cl atoms, thus displaying a slightly distorted octa-hedral geometry with no crystallographically imposed symmetry. The two six-membered chair chelate rings in the complex cation are in an anti conformatio...
