Synthesizing graphdiyne with a well-defined structure is great challenge. We reported herein rational approach to synthesize nanowalls using modified Glaser-Hay coupling reaction. Hexaethynylbenzene and copper plate were selected as monomer substrate, respectively. By adjusting the ratio of added organic alkali along amount monomer, proper ions was dissolved into solution, thus forming catalytic reaction sites. With rapid rate coupling, grew vertically at these sites first, then more...
Robust superhydrophobic foam is fabricated by combining an ordered graphdiyne-based hierarchical structure with a low-surface-energy coating. This shows not only superhydrophobicity both in air (≈160.1°) and oil (≈171.0°), but also high resistance toward abrasion cycles. Owing to its 3D porous structures numerous surfaces, it can easily separate from water efficiency good recyclability. As service our authors readers, this journal provides supporting information supplied the authors. Such...
Graphdiyne (GDY) is an ordered two-dimensional (2D) carbon allotrope comprising sp- and sp2-hybridized atoms with high degrees of π-conjugation, which features a natural band gap superior electric properties. However, the synthesis one- or few-layer GDY remains challenging because free rotation around alkyne-aryl single bonds lack thickness control. We report facile ultrathin single-crystalline film on graphene through solution-phase van der Waals epitaxial strategy. The weak...
A general and simple route to fabricate graphdiyne nanowalls on arbitrary substrates is developed by using a copper envelope catalysis strategy. The GDY/BiVO4 system but one example of combing the unique properites GDY with those target where improves photoelectrochemical performance dramatically.

Graphdiyne (GDY), a new kind of two-dimensional (2D) carbon allotropes, has extraordinary electrical, mechanical, and optical properties, leading to advanced applications in the fields energy storage, photocatalysis, electrochemical catalysis, sensors. However, almost all reported methods require metallic copper as substrate, which severely limits their large-scale application because high cost low specific surface area (SSA) substrate. Here, freestanding three-dimensional GDY (3DGDY) is...
Flexible pressure sensors that can robustly mimic the function of slow-adapting type I (SA-I) mechanoreceptors are essential for realizing human-like object manipulation in artificial intelligent (AI) robots or amputees. Here, we report a straightforward approach to highly sensitive and robust flexible with fast response time low operating voltage based on conductive micropyramids made polydimethylsiloxane/carbon nanotube composites. Both numerical simulations experimental studies show...
