Metal-organic Frameworks in Semiconductor Devices.

Metal-organic frameworks (MOFs) are a specific class of hybrid, crystalline, nano-porous materials made of metal-ion-based 'nodes' and organic linkers. Most of the studies on MOFs largely focused on porosity, chemical and structural diversity, gas sorption, sensing, drug delivery, catalysis, and separation applications. In contrast, much less reports paid attention to understanding and tuning the electrical properties of MOFs.

Electrochemical Potential-Driven High-Throughput Molecular Electronic and Spintronic Devices: From Molecules to Applications.

Molecules are fascinating candidates for constructing tunable and electrically conducting devices by the assembly of either a single molecule or an ensemble of molecules between two electrical contacts followed by current-voltage (I-V) analysis, which is often termed "molecular electronics". Recently, there has been also an upsurge of interest in spin-based electronics or spintronics across the molecules, which offer additional scope to create ultrafast responsive devices with less power consumption and lower heat generation using the intrinsic spin property rather than electronic charge. Researchers have been exploring this idea of utilizing organic molecules, organometallics, coordination complexes, polymers, and biomolecules (proteins, enzymes, oligopeptides, DNA) in integrating molecular electronics and spintronics devices.

Selective synthesis of single layer translucent cobalt hydroxide for the efficient oxygen evolution reaction.

We report the advancement of the catalytic activity for the oxygen evolution reaction using an orthogonal procedure to fabricate an α cobalt hydroxide hydrotalcite-like compound using rock salt and its transformation to a translucent single-layer cobalt hydroxide nanosheet by liquid phase exfoliation. The exfoliated single-layer nanosheet exhibited a remarkable mass activity of 153.8 A g-1 and a turn over frequency of 1.

Redox-active, pyrene-based pristine porous organic polymers for efficient energy storage with exceptional cyclic stability.

A novel class of pyrene-based conjugated porous organic polymers having an N-containing network was developed by employing Buchwald-Hartwig coupling for supercapacitor energy storage. The pristine polymer was found to exhibit a specific capacitance of 456 F g-1 at 0.5 A g-1 current density with excellent long-term cyclic stability.

Cobalt Phosphonates as Precatalysts for Water Oxidation: Role of Pore Size in Catalysis.

We report a simple approach for the synthesis of cobalt phosphonate (CoOP) nanocages with two distinct types of pore diameters by utilizing a novel tetra-constituent assembly of CoCl ⋅6 H O, nitrilotris(methylene)triphosphonic acid (NMPA), F127 surfactant, and polyvinyl alcohol (PVA, co-surfactant). Transmission electron microscopy images revealed the formation of large nanocages in spheres (pore diameter: 20-60 nm) and the existence of narrow micro/mesopores (pore diameter: 1.5-5 nm) on their walls.

Nano "Koosh Balls" of Mesoporous MnO : Improved Supercapacitor Performance through Superior Ion Transport.

Manganese dioxide nanomaterials with "Koosh-ball"-like morphology (MnO -KBs) as well as worm-like nanotubes (MnO -NWs) are obtained by employing Tween 20 as the reducing and structure-directing agent, and KMnO as a MnO precursor. Whereas the MnO -KBs are interconnected through tubular extensions, the MnO -NWs are largely disconnected. Both MnO -KBs and MnO -NWs have large BET surface areas (>200 m  g ), and are thermally robust up to 300 °C.
