Stable molecular switches Many single-molecule current have been reported, but most show poor stability because of weak contacts to metal electrodes. Jia et al. covalently bonded a diarylethene molecule graphene electrodes and achieved stable photoswitching at room temperature (see the Perspective by Frisbie). The incorporation short bridging alkyl chains between decoupled their pielectron systems allowed fast conversion open closed ring states. Science , this issue p. 1443 ; see also 1394
Inspired by the great development of graphene, more and works have been conducted to seek new two-dimensional (2D) materials with Dirac cones. Although 2D possess many novel properties physics, they are rare compared numerous materials. To provide explanation for rarity as well clues in searching systems, here we review recent theoretical aspects various materials, including silicene, germanene, graphynes, several boron carbon sheets, transition metal oxides (VO2)n/(TiO2)m (CrO2)n/(TiO2)m,...
Abstract Amongst various porous materials, noble metal aerogels attract wide attention due to their concurrently featured catalytic properties and large surface areas. However, insufficient understanding investigation of key factors (e.g. reductants ligands) in the fabrication process limits on-target design, impeding material diversity available applications. Herein, unveiling multiple roles reductants, we develop an efficient method, i.e. excessive-reductant-directed gelation strategy. It...
We systematically studied the Raman spectra of graphyne (GY) and graphdiyne (GDY), analyzing their features under mechanical strain by group theory first-principles calculations. The G bands in GY GDY were softened compared with that graphene, which provides a fingerprint useful detecting synthesis. established unified formulation to describe effects both uniaxial shear strains, combined this calculated results reveal relationship underlying changes evolution various strains. Each doubly...
A frequently stated advantage of gapless graphene is its high carrier mobility. However, when a nonzero bandgap opened, the mobility drops dramatically. The hardness to achieve and large on∕off ratio simultaneously limits development electronics. To explore underlying mechanism, we investigated intrinsic armchair nanoribbons (AGNRs) under phonon scattering by combining first-principles calculations tight-binding analysis. linear dependence effective mass on was demonstrated be responsible...

The possess ultrahigh specific surface area hierarchical interconnected pores, exhibiting superb gas/oil adsorption performance compared with all organic polymers to date.
Abstract By taking advantage of large changes in geometric and electronic structure during the reversible trans – cis isomerisation, azobenzene derivatives have been widely studied for potential applications information processing digital storage devices. Here we report an unusual discovery unambiguous conductance switching upon light electric field-induced isomerisation a robust single-molecule device first time. Both experimental theoretical data consistently demonstrate that sidegroup...

Electron transfer (ET) is crucial in many chemical reactions, but its mechanism and role are hardly understood nanobiotechnology due to the complexity of reaction species pathways involved. By modulating monitoring electron behavior at single-molecule level, we can better understand fundamental mechanisms ways control them for technological use. Here, unravel a single-electron catalysis under positively charged nanoconfinement. We demonstrate that both (2 + 2) (4 4) cycloadditions be...
Density functional theory (DFT) studies were performed to investigate the chlorination of graphene. Unlike hydrogenation and fluorination, where adsorption H F is always by covalent C–H/C–F bonding, Cl atoms generate various states when single-sided graphene exposed. In initial reaction stage, it forms Cl–graphene charge-transfer complex, C orbitals keep sp2 hybridization p-type doped. Further may form two configurations: one bonding pairs, structure atom close sp3 hybridization. With...

The electronic structures of BN-embedded graphene (BNG) were theoretically studied. A nonzero gap was found to exist in BNG regardless the edge (zigzag/armchair) and symmetries superlattice BN quantum dots (QDs). size is mainly determined by width carbon wall between neighboring QDs. It insensitive QDs, thus obeys a universal scaling law. This significant stable energy renders as promising way control properties graphene. comparison with antidot lattices nanoribbons also provided.

Noncovalent interactions involving aromatic rings, such as π-stacking and π-ion interactions, play an essential role in molecular recognition, assembly, catalysis, electronics. However, the inherently weak complex nature of these has made it challenging to study them experimentally, especially with regard elucidating their properties solution. Herein, noncovalent between π π-hole, cation, π-hole anion complexes nonpolar solution are investigated situ through single-molecule electrical...

The influence of lattice symmetry on the existence Dirac cones was investigated for two distinct systems: a general two-dimensional (2D) atomic crystal containing atoms in each unit cell and 2D electron gas (2DEG) under periodic muffin-tin potential. A criterion derived tight-binding approximation crystal. When transfer hoppings are assumed to be single functions distance between atoms, it shown that probability observing gradually decreases before being reduced zero when changes from...
