Ferrocene has been extensively used for the design of chromophores with reversible electrochemical properties.

The title compound, [Fe(C(5)H(5))(C(19)H(16)O(2)P)], obtained serendipitously during recrystallization of 1-hydroxy-benzotriazolyl (S(p))-2-(diphenyl-phosphino)ferrocene-1-carboxyl-ate from meth-anol, crystallizes in the chiral space group P2(1)2(1)2(1). Its crystal structure not only confirms the anti-cipated absolute configuration but also establishes a rather regular geometry for the ferroce...

We report a new DNA and polymerase detection method that utilizes the competition between a ferrocene-labeled PNA probe and the target DNA or a polymerase-elongated DNA primer to hybridize with a DNA probe/template. Due to the electrostatic interaction between the negative DNA backbones and a negatively-charged electrode, the results of the competition were reflected in the electrochemical sign...

[structure: see text] Ferrocene compounds bearing multiple amido groups selectively bind with the H(2)PO(4)(-) ion over other anions. The one-arm receptors form 1:1 complexes with the H(2)PO(4)(-) ion, whereas the two-arm receptors can accommodate two H(2)PO(4)(-) ions. The complexation modes and binding strengths are deduced from the NMR, calorimetry, fluorescence, and cyclic voltammetry studi...

1,1 0-Ferrocene dicarboxylic acid pyridin-4-yl ester (1) is prepared from 1,1 0-ferrocene dicarbonyl chloride and 4-hydroxypyridine. This new bidentate ferrocenoyl ligand reacts with the monocationic complex [(g-p-cymene)2Ru2(l-OH)3] + to give the dicationic complex [(g-p-cymene)2Ru2(l-OH)2(1,1 0(NC5H4–OOC)2–Fc)] 2+ (2) (Fc: C5H4–Fe–C5H4), isolated as a tetrafluoroborate salt. The single-crysta...

Nanoparticle-mediated intervalence transfer was reported with ferrocene moieties that were attached onto the ruthenium nanoparticle surface by ruthenium-carbene pi bonds. The resulting particles exhibited two pairs of voltammetric waves with a potential spacing of about 200 mV and a rather intense absorption peak in the near-infrared range (approximately 1930 nm) at mixed valence. Both features...

A donor–acceptor linked triad with a short spacer (Fc-ZnP-C60) 1 was designed and synthesised to attain the longest charge-separation lifetime, 630 ms, ever reported for triads at room temperature. The ferrocene electron donor and fullerene electron acceptor of triad 1 are attached to imidazole rings fused to opposite b,b0-pyrrolic positions of the zinc porphyrin. After excitation of the porphy...

A focused series of novobiocin derivatives containing a ferrocene unit together with their corresponding organic novobiocin analogues have been synthesized in modest to good yields. These compounds were screened for biological activity against a chloroquine-sensitive strain of Plasmodium falciparum (3D7) and human breast cancer cell line (HCC38). With the exception of compounds 5c and 5d, the g...
