Abstract Diamondene is a new kind of two dimensional carbon allotrope with excellent properties and passivation approaches are often used to reduce the extremely high pressure required during its fabrication. When a one-end-clamped diamondene ribbon is hydrogenated on one surface, the ribbon tends to bend and vibrate due to asymmetric layout of C-H bonds on two surfaces. In the present work, the vibration behavior, including natural curvatures and vibration frequencies of diamondene ribbons, were investigated by molecular dynamics simulations. Results indicate that the natural curvature radius of a narrow diamondene ribbon is close to 12.17 nm at a temperature below 150 K, which is essential for fabricating an arc nanodevice. The first order frequency (f1) of a cantilever beam made from the ribbon follows traditional beam vibration theory if the slenderness ratio is low. In particular, f1 increases logarithmically at temperature below 50 K, but changes slightly between 50 K and 150 K. It suggests a design scheme for a nanoresonator with temperature-controlled frequency.

Liquid Phase Exfoliation

Fluorinated single-layer diamond (“F-diamond”) is a new form of two-dimensional carbon allotrope. Herein, poly(dicarbon monofluoride) (C<sub>2</sub>F)<sub>n</sub> that is essentially made of stacked layers of “F-diamane” has been synthesized and exfoliated in a variety of solvents to yield well-dispersed ultrathin sheets. Microscopic and spectroscopic analyses revealed that the exfoliated sheets retained the “F-diamane”-like structure. The experimental results are supported by the density functional theory (DFT) calculations.

High Fluorescence

Graphdiyne (GD), a new kind of two-dimensional carbon allotrope consisting of a hexagonal ring and a diacetylenic linkage unit, is observed to exhibit a high fluorescence quenching ability and can be used as a new platform for fluorescence sensing, where GD oxide, the oxidized form of GD, is found to exhibit higher quenching ability than GD.
