Ferrocene Macrocyclic Schiff Base Complex: Synthesis, Structure and Recognition Properties for Dual Hg2+ and Cu2+

A probe based on ferrocene structure has been designed, synthesized and elucidated from the single crystal X-ray method. It demonstrated fluorescence response to Hg2+ and Cu2+ in CH3OH. The results indicated that the title complex could be applied in the multianalyte detection. Binding ability of receptor 3 in CH3OH was tested for various cations (Fe3+, Co2+, Cu2+, Zn2+, Cd2+, Hg2+, Pb2+, and Ba2+ in water). The computed binding constants for Hg2+ and Cu2+ indicated a distinct absorbance shift. The receptor is an attractive array due to its distinct absorbance shift profile in a semi-aqueous phase, making it applicable in biology, environmental sciences and material chemistry.

Synthesis and characterisation of a Cd(II) complex with a chiral framework constructed from achiral 1,1′-[bis-3-(3-pyridyl)pyrazol-5-yl]ferrocene via spontaneous resolution

The chiral Cd(II) complex {[Cd(L)(CH3COO)2(H2O)]H2O}n {L = 1,1′-[bis-3-(3-pyridyl)pyrazol-5-yl]ferrocene} has been synthesised. The Cd(II) ion is coordinated by two pyridyl nitrogen atoms, two chelating acetate anions and one water molecule, showing a distorted pentagonal-bipyramidal coordination environment. Each ligand L serves as a bisconnector, bridging two Cd atoms through its two pyridyl moieties, to afford an infinite 1D left-handed helical chain along the a-axis with a short pitch of 5.8761 (9) A. Moreover, all of the left-handed helical chains are joined by hydrogen bonds to form a left-handed homochiral crystal.

HETEROJUNCTION PHOTOELECTRODES: IV. ELECTROCHEMISTRY AND PHOTOELECTROCHEMISTRY AT INDIUM TIN OXIDE/NONAQUEOUS ELECTROLYTE INTERFACES.

The kinetic facility of charge transfer was studied by cyclic voltammetry (CV) at Sn-doped indium oxide (ITO) electrode/acetonitrile interfaces for 18 one-electron outer-sphere redox systems. The results were compared with Pt, and the relative trends in redox kinetics were analyzed from a phenomenological viewpoint. The strong dependency of redox kinetics at the ITO surface on the location of electrolyte energy levels (redox potential) argues against the complete transparency of the space-charge layer in ITO to electron tunneling processes. The new results seem to be consistent with a model proposed by previous authors, which considers mediation of electron tunneling by deep-lying donor states in the space-charge region. For positive-lying redox systems, this mediation step is rate determining.

Redox-Guest-Induced Multimode Photoluminescence Switch for Sequential Logic Gates in a Photoactive Coordination Cage

Molecular or supramolecular level photoluminescence (PL) modulation combining chemical and photonic input/output signals together in an integrated system can provide potential high-density data memorizing and process functions intended for miniaturized devices and machines. Herein, a PL-responsive supramolecular coordination cage has been demonstrated for complex interactions with redox-active guests. PL signals of the cage can be switched and modulated by adding or retracting Fc derivatives or converting TTF into different oxidation states through chemical or photochemical pathways. As a result, reversible or stepwise PL responses are displayed by these host?guest systems because of the occurrence of photoinduced electron-transfer (PET) or fluorescence resonance energy transfer (FREnT) processes, providing unique nanodevice models bearing off/on logic gates or memristor-like sequential memory and Boolean operation functions.

Synthesis, characterization, and antitumor activities of 1,1?-diacetylferrocene dihydrazone containing phenolic group and its complexes with Pd(II) and Pt(II)

A ferrocenyl ligand was prepared from condensation of 1,1?- diacetylferrocene dihydrazone with salicylaldehyde. The ligand forms 1:1 complexes with Pd(II) and Pt(II) in good yield. Characterization of the ligand and complexes was carried out using elemental analysis, infrared study, 1H and 13C nuclear magnetic resonance, and electronic absorption spectra. Anticancer activity of the prepared ligand and its complexes against human breast cancer cell line MCF-7 was determined, and the results were compared with the activity of the commonly used anticancer drug cisplatin. The results suggested that the prepared compounds possess significant antitumor activity comparable to the activity of cisplatin.

Photolysis of diacylferrocenes and their photo-ligand exchange reactions with 1,10-phenanthroline

The photolysis of 1,1?-diacylferrocenes Fc(COR)2 (Fc = Ferrocenyl, R = CH3,Ph) in the presence of 1,10-phenanthroline (phen) in deoxygenated acetonitrile under irradiation with visible light has been studied. In these photolysis systems the phen has two important roles to play: one is to stabilize the photo-liberated Fe2+ by coordination, and the other is to promote the photolysis through photo-ligand exchange. Under this condition the photoproducts were isolated in definite composition and characterized by single crystal X-ray diffraction, 1H NMR spectroscopy, IR spectroscopy, photolysis-cyclic voltammetry and elemental analysis. The mechanism of the reactions was demonstrated to be charge transfer from metal to acylcyclopentadienyl ring, leading to cleavage of the bond between them. The phen attacks the Fe2+ ion to give the stable tris (1,10-phenanthroline) iron(II) complex cation and the acylcyclopentadienyl ring detaches from the Fe2+ ion, giving the enolate anion in the outer sphere of the complex.

Visual detection and removal of mercury ions by a ferrocene derivative

New ferrocene naphthyridine derivatives were successfully synthesized. The di-substituted ferrocene derivative FecDN behaves as a selective visual chemosensor for mercury ions, exhibiting a rapid and clearly visible precipitation with good selectivity (precipitation) and sensitivity (0.01 muM). The interaction of the ferrocene derivatives and metal ions was investigated by ultraviolet-visible spectroscopy (UV-vis), electrochemical methods, 1H NMR, as well as infrared (IR), and energy dispersive X-ray spectroscopy (EDX). The application of FecDN in the detection and removal of mercury ions is very simple, rapid, and intuitive.

Reversible double oxidation and protonation of the non-innocent bridge in a nickel(II) salophen complex

Substitution on the aromatic bridge of a nickel(II) salophen complex with electron-donating dimethylamino substituents creates a ligand with three stable, easily and reversibly accessible oxidation states. The one-electron-oxidized product is characterized as a nickel(II) radical complex with the radical bore by the central substituted aromatic ring, in contrast to other nickel(II) salen or salophen complexes that oxidize on the phenolate moieties. The doubly oxidized product, a singlet species, is best described as having an iminobenzoquinone bridge with a vinylogous distribution of bond lengths between the dimethylamino substituents. Protonation of the dimethylamino substituents inhibits these redox processes on the time scale of cyclovoltammetry, but electrolysis and chemical oxidation are consistent with deprotonation occurring concomitantly with electron transfer to yield the mono- and dioxidized species described above.

ELECTRONIC STRUCTURE OF FERROCENE DERIVATIVES STUDIED BY He(I) PHOTOELECTRON SPECTROSCOPY AND CNDO/2 METHOD

The effect of substituents in the Cp ligands on the electronic structure has been studied for the 1,1′-disubstituted ferrocenes Fe(CpX)2, with X = C2H5, OCH3, CN, COCH3, COOCH3, OOCCH3, CH2C6H5, or C6H5, by UV photoelectron spectroscopy and by CNDO/2 calculations.The energy gap between the 2E2g and 2A1g ion states, 0.36 eV in the parent ferrocene, is affected only by the COCH3 and COOCH3 substituents, which lower it to 0.22 and 0.28 eV, respectively.Splitting of e1u(?) level due to the lowering of the symmetry is the only effect observed in the photoelectron spectra.There is a strong conjugation between the phenyl and cyclopentadienyl ?-orbitals in 1,1′-diphenylferrocene.The changes in the a1g(d) ionization energy calculated by the DeltaSCF method using CNDO/2 total energies are in a good agreement with the experimental data.
