Substituent effects in the iron 2p and carbon 1s edge Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy of ferrocene compounds

The iron 2p and carbon 1s near-edge X-ray absorption fine structure (NEXAFS) spectra of substituted ferrocene compounds (Fe(Cp-(CH3) 5)2, Fe(Cp)(Cp-COOH), Fe(Cp-COOH)2, and Fe(Cp-COCH3)2) are reported and are interpreted with the aid of extended Hiickel molecular orbital (EHMO) theory and density functional theory (DFT). Significant substituent effects are observed in both the Fe 2p and C 1s NEXAFS spectra. These effects can be related to the electron donating/withdrawing properties of the cyclopentadienyl ligands and their substituents as well as the presence of pi* conjugation between the cyclopentadienyl ligand and unsaturated substituents.

Electrical current oscillations in vapor-adsorbed ferrocene derivatives having two substituted groups

Oscillations in electrical current as a function of time have been observed in a specific temperature range in the samples of 1,1?-diacetylferrocene and 1,1?-ferrocenedicarboxylic acid with adsorbed ethanol vapor in a sandwich-type cell. The frequency of current oscillations has been found to decrease with bias voltage and sample temperature and to increase with vapor pressure. The frequency of current oscillations for the mono-group substituted derivatives is higher than the corresponding frequency for the derivatives having two substituted groups. Again, the frequency of oscillations for -COCH3 group substituted derivatives is higher than the corresponding value for -COOH group substituted derivatives. The observation of current oscillations is possibly associated with some kind of time dependent phase changes, arising from the structural nonrigidity of the molecules, in the solid-ethanol vapor system at the sample surface layer. The “ball-bearing” motion of the cyclopentadienyl rings of ferrocene unit, nature and number of substituted groups, cooperative interaction of the neighboring molecules influence the structural nonrigidity and hence the oscillatory behavior of current. Reasons are given for ruling out other models of current oscillations in semiconductors.

Investigation of processing effects on the corrosion resistance of Ti20Mo alloy in saline solutions

The electrochemical properties of Ti20Mo alloys prepared using different fabrication procedures, namely cold crucible levitation melting (CCLM) and powder sintering, were investigated using linear potentiodynamic polarization and EIS measurements. The surface condition was established using AFM, with the observation of a more porous surface finish in the case of powder sintering. A major effect of surface conditioning on the corrosion resistance of Ti20Mo alloys was observed, where the compact finish exhibits a superior corrosion resistance in chloride-containing saline solutions. Less insulating surfaces towards electron exchange resulted for the more porous finish as revealed by scanning electrochemical microscopy (SECM).

1-Ferrocenylcyclopropene and 1-ferrocenylcyclopropyl cation

Dehydrobromination of cis and trans isomers of 1-bromo-2-ferrocenylcyclopropanes affords 1-ferrocenylcyclopropene. Its protonation with HBF4 results in 1-ferrocenylcyclopropylium tetrafluoroborate, which alkylates N,N-dimethylaniline in para position to yield 1-(p-dimethylaminophenyl)-1-ferrocenylcyclopropane. 1-Ferrocenylcyclopropene reacts with 1,3-diphenylisobenzofuran to give the classical [4+2]-cycloaddition product. Its structure as exo-2-ferrocenyl-1,5-diphenyl-6,7-benzo-8-oxatricyclo [3.2.1.02.4]oct-6-ene was established based on the data from X-ray diffraction analysis.

Diamond nanostructures and nanoparticles: Electrochemical properties and applications

Macro-sized diamond films have been widely applied as the electrode for electrochemical and electroanalytical applications. Due to the non-uniform doping in diamond, boundary effects, and the varied ratios of graphite to diamond, only averaged electrochemical signals are detected over the full electrode. The studies of diamond electrochemistry at the nanoscale are thus highly required. In this chapter we overview recent progress and achievements about electrochemical properties and applications of diamond nanostructures and nanoparticles. After a brief introduction of the formation of these nanostructures and nanoparticles, electrochemical behavior of diamond nanostructures (e.g., diamond nanotexures, nanowires, networks, etc.) and nanoparticles (undoped, doped nanoparticles) in the presence/absence of redox probes is summarized. Their electroanalytical (e.g., electrochemical, biochemical sensing, etc.) and electrochemical (e.g., energy storage using capacitors and batteries, electrocatalysis, etc.) applications are shown. Diamond nanoelectrode array is introduced and highlighted as a promising tool to investigate diamond electrochemistry at the nanoscale as well.

COMPARISON OF THE ELECTRONIC STRUCTURE OF DISUBSTITUTED FERROCENES.

We have measured the optical absorption of gaseous ferrocene, 1,1 prime -dimethylferrocene, 1,1 prime -dibromoferrocene, and 1,1 prime -dichloroferrocene using synchrotron radiation. From these data we have estimated the ligand field parameters and noted increasing e//2//g(d) to Cp( pi ) overlap with increasing charge transfer from the Cp ring to the substitution. The optical absorption spectra for ferrocene, dibromoferrocene, and dichloroferrocene are remarkably similar. The halogen substitutions result in greater Cp( pi ) to e//2//g-(d(x2-y2)) hybridization. The e//2//g orbitals become more bonding while the a//1//g and e//1//g orbitals become more non-bonding or antibonding. This change is reflected in a change of the ligand field parameters.
