A series of vinylferrocene derivatives were synthesized from the reaction of ferrocenecarboxaldehyde, alcohol, and triphenylphosphonium bromide in a one-pot, solid-state reaction. Their third-order nonlinear optical (NLO) properties were evaluated in N,N-dimethylformamide at 800 nm using femtose...

Protocols for anionic polymerization of vinylferrocenes in bulk (b) and solution (s) are reported. Polymerization of vinylferrocenes bearing one or multiple (2–4) vinyl groups yielded linear polyvinylferrocene PVF-1(b, s) or cross-linked polyvinylferrocenes PVF-2 – PVF-4(b, s), respectively. F...

Efficient syntheses of 1′-trimethylsilylethynyl-, 1′-ethenyl-, and 1′-formyl-1-ethynylferrocenes are reported. The majority of these compounds exhibit chemically reversible ferrocene-based oxidation processes from cyclic voltammetry and thereby constitute key synthons for the development of r...

In the present study, the use of a carbon paste electrode modified by ethynylferrocene (EF) and NiO/MWCNT nanocomposite prepared by a simple and rapid method was described. The modified electrode showed an excellent character for electrocatalytic oxidization of glutathione (GSH) and acetaminophe...

Ethynylferrocene-functionalized titanium dioxide nanoparticles (TiO2-eFc) were synthesized, for the first time ever, by a modified two-phase hydrothermal method. Transmission electron microscopic measurements showed that the nanoparticles were rather uniform in size, with an average diameter of ...

A protonation of ethynylferrocene by nafion in sc-CO2 in the presence of triphenylphosphine (PPh3) or 1,2-bis(diphenylphosphino)ethane (DPPE) leads to a formation of novel (1-ferrocenylvinyl)phosphonium or ferrocenyl substituted bisphosphonium salt isolated as tetrafluoroborates 3 and 4, respect...

A superacidic polymer Nafion protonates ferrocenylacetylene (1) in sc−CO2 (35 °C, 9 MPa) to from the α-ferrocenylvinyl cation, FcC+=CH2 (2, Fc = ferrocenyl). Carbocation 2 in situ alkenylates dimethyl sulfide (25 MPa) or 1,4-dithiane (35 MPa) to give 1-ferrocenylvinyl sulfonium salts isolated ...

The use of organozinc reagents in the synthesis of terminal alkene derived cyclic halogenated phosphazenes has been explored by the reactions of allylzinc bromide and ethynylferrocene derived fluorophosphazenes. The reaction of monoethynylferrocene derived fluorophosphazene, [(FcCC)(F)PN](PNF2)2...

In vivo tracking of transplanted stem cells has been a central aim of stem cell therapy. Although many tracking systems have been introduced, no method has yet been validated for clinical applications. We developed a novel sophisticated peptide (GV1001) that mimics hTERT (human telomerase revers...

The iron precursor of lithium iron phosphate (LiFePO4) is highly prone to oxidation to Fe3+ during the hydrothermal synthesis. The Fe3+ impurities in LiFePO4 restrict the conduction path of Li+ ions in LiFePO4, which negatively affect the cell performance. In this paper, we report that ferrocene...

Herein we report a sandwich-type electrochemical immunosensor for sensitive detection of cardiac troponin I (cTnI) using a new composite of carboxyl-terminated ionic liquid and helical carbon nanotubes (CIL-HCNTs) as platform and ferrocenecarboxylic acid (Fc-COOH) as signal label. The composite ...

During the past decade, accumulating studies have been conducted on the mesoporous silica materials as the matrix of controlled drug-delivery, in which the complicated post-synthesis procedures are often involved with the molecular design to achieve the efficacy. In this study, a simplified drug...

The microwave spectrum was measured for ferrocenecarboxylic acid in the 4.8–9.8 GHz range using a pulsed-beam Fourier transform microwave spectrometer. 27 transitions were measured and assigned, which include a-, b-, and c-type rotational transitions. From the measured transitions, the rotation...

The binding of titanocene to DNA and RNA was examined by means of electrospray mass spectrometry. Titanocene served as a model for its therapeutically active derivatives. The binding preferences were probed by competition experiments with oligonucleotides of varying nucleobase compositions and s...

Nickel silicide nanocrystal containing Si–Ni–C–N multiphase ceramics were synthesized by bulk pyrolysis of the mixture of polysilazane (PSZ) and nickelocene (NiCp2) at high temperature. The pyrolysis behavior of the precursors was investigated by TGA/DSC-Mass Spectrometry. The yield of the ce...

Nickelocene [bis(η5-cyclopentadienyl)nickel: Ni(C5H5)2, electron spin S=1, the ground state configuration 3A2g] is paramagnetic and belongs to a typical molecule-based magnet. Heat capacities of nickelocene have been measured at temperatures in the 3−320 K range by adiabatic calorimetry. By com...

In this paper we describe the syntheses and characterization of novel axially chiral metallacyclic complexes. Contrary to previously described synthesis of 9-nickelafluorenyllithium complexes, reaction of dilithium ligand afforded nickelacyclic analogue of nickelocene. Similar compounds were obt...

In this work, a novel NiO/Co3O4 nanoheterostructure was fabricated via a simple pyrolysis treatment of nickelocene (NiCp2) filled ZIF-67. With remarkable structural features, the obtained NiO/Co3O4 hybrids exhibit high specific capacitance of 405 F g-1 at 1 A g−1 and high cycling stability (97.4...

New catalytic systems based on nickelocene were used as initiators in polymerization of ethyl acetate carbene derived from ethyl diazoacetate. Nickelocene itself and nickelocene activated with n-butyllithium or diphenylmethyllithium led to the formation of oligomers with average molecular weight...

Deposition studies have established maximum values for the adsorption of chromocene on dehydroxylated silicas. The process of chemisorption of chromocene changes from reaction of predominantly two to one hydroxyl group as the temperature of silica increases from 100 to 800 °C. Chromocene, depos...
