The charge transfer compounds (TTF) FeCl 3 , (TTF) 3 FeBr 3 , (TTF)RuCl 3 -2H.0, (TTF)RhCl 3 .H 2 0, and (TTF)IrCl 4 -CH 3 OH were prepared from reaction of solutions of TTF (tetrathiafulvalence) and the metal halide. Magnetic susceptibility and spectroscopic (electronic, vibrational, XPS, and EPR) evidence indicate that there is incomplete charge transfer from the TTF donor to iron, and that there is essentially complete charge transfer to ruthenium, rhodium, and iridium. The experimental evidence indicates that two electrons are transferred in the rhodium compound. The electrical conductivities of powdered samples of the iron compounds are five orders of magnitude greater than those of the ruthenium, rhodium, and iridium compounds, being 6-10 S-cm-'at room temperature. All of the compounds exhibit semiconducting behavior which may be described by R mobility 2 model having a temperature dependent preexponential term and relatively small activation energies.

Metal complexes with Schiff base ligands have been suggested as potential phosphors in electroluminescent devices. In the title complex, tetrakis[6-methyl-2-({[(pyridin-2-yl)methyl]imino}methyl)phenolato-1:2κ(8)N,N',O:O;3:2κ(8)N,N',O:O]trizinc(II) hexafluoridophosphate methanol monosolvate, [Zn3(C14H13N2O)4](PF6)2·CH3OH, the Zn(II) cations adopt both six- and four-coordinate geometries involving the N and O atoms of tetradentate 6-methyl-2-({[(pyridin-2-yl)methyl]imino}methyl)phenolate ligands. Two terminal Zn(II) cations adopt distorted octahedral geometries and the central Zn(II) cation adopts a distorted tetrahedral geometry. The O atoms of the phenolate ligands bridge three Zn(II) cations, forming a dicationic trinuclear metal cluster. The title complex exhibits a strong emission at 469 nm with a quantum yield of 15.5%.

Poly(1,6-heptadiyne) derivatives with phenoxy and 3,7-dimethyloctyloxyphenoxy substituents were synthesized using metathesis polymerization. Polymerizations using MoCl 5 as the sole catalyst gave high yields and the resulting polymers were completely soluble in organic solvents. The polymers' structures and thermal properties were characterized using NMR and UV-Vis spectroscopy, as well as with TGA and DSC thermograms. From the analysis of the high-resolution 13 C-NMR spectra, we was found that these polymers contain six-membered rings.The number-average molecular weights and polydispersities of the polymers were ca. 7.0~20 Ý10 3 and 3.1~5.8, respectively. The glass transition temperatures of the polymers were found to be in the range 91~159 o C.
