Electron transport of bis(terpyridine)iron(II) complex wires on a semiconducting electrode
Journal of Electroanalytical Chemistry, 2016Abstract The electron transport phenomena of ferrocene- and triarylamine-terminated bis(terpyridine)iron(II) complex wires on p-type silicon(111) electrodes were electrochemically investigated. The ferrocene unit at the terminus of the wire exhibited the large redox peak separation in cyclic voltammogram indicating the slow electron transport, while ...

AbstractMitochondria are indispensable in maintaining hematopoietic stem cells (HSCs), and mitochondrial complex II (MCII) has been recognized as a key component of HSCs. However, the physiological role of MCII on long-term hematopoiesis and hematopoietic reconstitution capacity remains unknown.

In chloroplasts, photosynthetic electron transport complexes interact with each other via the mobile electron carriers (plastoquinone and plastocyanin) which are in surplus amounts with respect to photosystem I and photosystem II (PSI and PSII), and the cytochrome b 6 f complex.

We have studied the inhibition of photosynthetic electron transport by UV-A (320-400 nm) radiation in isolated spinach thylakoids. Measurements of Photosystem II (PSII) and Photosystem I activity by Clark-type oxygen electrode demonstrated that electron flow is impaired primarily in PSII.

Structure-(Dys)function Relationships in Mitochondrial Electron Transport Chain Complex II?
Science of Aging Knowledge Environment, 2003It has been postulated that mitochondrially derived reactive oxygen species (ROS) play a major causative role in aging processes. The primary sources of these oxidants are believed to be complexes I and III of the electron transport chain, with little evidence supporting oxidant formation at complex II (succinate dehydrogenase).

Electronic Transport Properties of Spin-Crossover Magnet Fe(II)-N4S2 Complexes
Chinese Journal of Chemical Physics, 2018Spin-crossover (SCO) magnets can act as one of the most possible building blocks in molecular spintronics due to their magnetic bistability between the high-spin (HS) and low-spin (LS) states. Here, the electronic structures and transport properties through SCO magnet Fe(II)-N4S2 complexes sandwiched between gold electrodes are explored by performing ...

Abstract A novel ligand 3,6-bis(1,10-phenathroline-[5,6-d] imidazole-2-yl)carbazole (Bpic) containing hole- and electron-transporting groups was firstly designed. Its polymeric complexes of Bpic with Cu(∥), Zn(∥) were successfully synthesized. The UV-vis absorption, fluorescence spectra and thermal properties of these complexes were investigated.

The present work reports a tripodal scaffold for bis(terpyridine)-Fe(II) oligomer wires on an Au(111) surface: the tripodal scaffold realised both orthogonality of the oligomer wires, and fast interfacial electron transfer through the oligomer wires.

Abstract Rate constants for quenching emission from photoexcited tris-(2,2′-bipyridine)- and tris(1,10-phenanthroline)Ru(II) complexes by bipyridinium ion vary with the redox potential of the quencher. Annihilation of the geminate ion pairs at the quenching step can be reduced by the addition of EDTA.

Vanadium compounds are promising metallodrug candidates, with well‐documented antidiabetic, antitumor, and anti‐Alzheimer's activities. In search for the long‐term beneficial or adverse effects of antidiabetic vanadyl complexes, we serendipitously discovered that the vanadyl complexes VOp‐dmada exerted pro‐healthy aging effects ...
