The use of Ir(III) complexes in photo-responsive molecular devices for oxygen gas sensing is reviewed. Attention is focused on the immobilization of Ir(III) complexes in organic or inorganic host materials such as polymers, silica and clays in order to enhance robustness and reliability. Our recent works on constructing nanometer-thick films comprised of cyclometalated cationic Ir(III) complexe...

High axiality in double unsupported phenoxide-bridged DyIII and HoIII complexes promotes slow relaxation of magnetisation high Ueff the dysprosium derivative.

The Delta- and Lambda-isomerism of octahedral metal complexes is employed as a source of chirality for inducing chiral nematic phases. By applying a wide range of chiral metal complexes as a dopant, it has been found that tris(beta-diketonato)metal(III) complexes exhibit an extremely high value of helical twisting power. The mechanism of induction of the chiral nematic phase is postulated on th...

A new class of donor–acceptor type luminescent bis(alkynyl)gold(III) N^C complexes has been synthesized and characterized. These gold(III) complexes not only exhibit high photoluminescence quantum yields of up to 0.81, but also interesting mechanochromic luminescence behaviors that are reversible. Upon grinding, a dramatic luminescence color change from green to red can be observed in solid sam...

The RM1 quantum chemical model for the calculation of complexes of Tm(III), Yb(III) and Lu(III) is advanced. Subsequently, we tested the models by fully optimizing the geometries of 126 complexes. We then compared the optimized structures with known crystallographic ones from the Cambridge Structural Database. Results indicate that, for thulium complexes, the accuracy in terms of the distances ...

Some new surfactant-cobalt(III) complex ions of the type, cis-[Co(X)2(C11H23NH2)2] 3+ (where X= ethylenediamine or 2,2’ bipyridyl or 1,10-phenanthroline) and cis-α-Co(trien) (C11H23NH2)2] 3+ were synthesized and characterized by IR, NMR, UV-Visible spectra, elemental and metal analysis. The critical micelle concentration (CMC) values of these surfactant-cobalt(III) complexes in aqueous solution...

A new macrocyclic Schiff base complexes were prepared in the presence of lanthanide metal ion[La(III), Ce(III) and Gd(III)] by the reaction of 2,6 – diamino pyridine, benzoyl aceton and metal ion as template effect in the molar ratio of 2: 2: 1 respectively. The lanthanide metal complexes were characterized and investigated by using; 1 HNMR, FTIR, UV/Visible spectroscopy, Elemental analysis (C....

The respiratory chain in the inner mitochondrial membrane contains three large multi-enzyme complexes that together establish the proton gradient for ATP synthesis, and assemble into a supercomplex. A 19-Å 3D map of the 1.7-MDa amphipol-solubilized supercomplex I(1)III(2)IV(1) from bovine heart obtained by single-particle electron cryo-microscopy reveals an amphipol belt replacing the membrane ...

La RNA-binding protein is a transcription termination factor that facilitates recycling of template and RNA polymerase (pol) 111. Transcription complexes preassembled on immobilized templates were depleted of pol III after a single round of RNA synthesis in the presence of heparin and sarkosyl. The isolated complexes could then be complemented with highly purified pol III and/or recombinant La ...
