The self-assembly of rhenium-based rectangular boxes with a large inner cavity can be achieved via a simple one-step synthetic route; these molecules selectively recognize planar aromatic molecules, benzene in particular.
Highly efficient photoswitching tetranuclear rhenium(I) tricarbonyl diimine complexes with a stilbene-like bridging ligand are reported. The ability to directly populate excited states localized on the bridging ligand is the key for the observed efficient photoisomerization.
A convenient rhenium-based multimodal mitochondrial-targeted probe compatible with Synchrotron Radiation X-ray Fluorescence nano-imaging.
The structures and properties of rhenium nitrides are studied with density function based first principle method. New candidate ground states or high-pressure phases at Re:N ratios of 3:2, 1:3, and 1:4 are identified via a series of evolutionary structure searches. We find that the 3D polyhedral stacking with strong covalent N-N and Re-N bonding could stabilize Re nitrides to form nitrogen rich...
Dichroic behaviors of layered ReS2 have been characterized using angular dependent polarized-absorption and resistivity measurements in the van der Waal plane. The angular dependent optical and electrical measurements are carried out with angles ranging from = 0 ̊ (E || b) to = 90 ̊ (E b) with respect to the layer crystal’s b-axis. The angular dependence of polarized energy gaps of ReS2 sho...
Reaction of the doubly-bridged biscyclopentadienes (C5H4(EMe2))(C5H4(SiMe2)) (E = Si(1a), or C(1b)) with Re2(CO)10 in refluxing mesitylene gave the corresponding dirhenium carbonyl complexes [(η(5)-C5H3)2(EMe2)(SiMe2)][Re(CO)3]2 (trans-2a,b and cis-2a,b), and the desilylated products [(η(5)-C5H4)2(EMe2)][Re(CO)3]2 (3a,b). Photolysis of trans-2a,b with a series of aryl halides in benzene results...
