BODIPY (4,4-difluoro-4-bora-3a,4a-diaza-s-indacenes) dyes possess intense absorption profiles that can be exploited in various light harvesting applications. However, redox stability and optimization of frontier molecular orbital energies in these dyes are critical for their successful incorporation into new solar cell materials. This article describes the synthesis and characterization of a fa...

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...
