Graphdiyne (GD), a novel carbon allotrope with a 2D structure comprising benzene rings and carbon-carbon triple bonds, is successfully integrated with ZnO nanoparticles by a wet chemistry method. An ultraviolet photodetector based on these graphdiyne:ZnO nanocomposites exhibits significantly enhanced performance in comparison with a conventional ZnO device. GD may have diverse applications in future optoelectronics.

An explosion approach was developed for efficiently preparing graphdiynes (GDYs) at 120 °C in air without any metal catalyst. The GDYs show great superiority in terms of thermal stability, conductivity (20 S m) and surface area (up to 1150 m g), and can be applied as promising anodes for storing lithium/sodium ions.

all-carbon materials hold great fascination because of their superior properties and promising applications. Herein, we presented the first demonstration for the use of graphdiyne (GDY) as photothermo-acoustic wave nanotransducers for simultaneous effective photoacoustic imaging (PAI) and photothermal therapy (PTT) in living mice. With a large extinction coefficient in near-infrared (NIR) region, upon irradiated by 808 nm laser, GDY not only exhibits a stable photothermal performance with a high photothermal conversion efficiency of 42%, but also provides an excellent photoacoustic response. Owing to its good biocompatibility modified with PEGylation, GDY can be simultaneously used as PAI probe and PTT agent and exhibits an efficient photothermal ablation of cancer cells in living mice. This work opens a new way into the development of 2D graphdiynes as novel theranostic platform for cancer treatment.

As a new member of carbon allotropes, graphdiyne is a promising material with excellent electronic performance and high elasticity, indicating the possibility of graphdiyne to serve as the building blocks in flexible electronics. However, precise positioning/patterning of graphdiyne is still a challenge for the realization of large-area and flexible organic electronic devices and circuits. Here, the direct in situ synthesis of patterning graphdiyne stripe arrays dominated by the superlyophilic grooved templates is reported, whereas the superlyophilicity of grooved templates plays a key role in allowing continuous mass transport of raw reactants into the microscale spacing. After the completion of cross-coupling reaction procedure, precisely patterned graphdiyne stripes can be generated accordingly. The size of graphdiyne stripe arrays is depending on the silicon substrate size (1 cm × 1.5 cm), and the layer thickness can be manipulated from just several nanometers to hundreds of nanometers by varying the primary concentration of hexaethynylbenzene monomers. As a proof-of-principle demonstration, a stretchable sensor based on the graphdiyne stripe arrays is performed to monitor the human finger motion. It is expected that this wettability-facilitated strategy will provide new insights into the controlled synthesis of graphdiyne toward promising flexible electronics and other optoelectronic applications.

Comparing to other carbon materials, the general graphyne structure is much superior in terms of adaptable bandgap, uniformly distributed pores, more design flexibility, easier for chemical synthesis, pliable electronic properties, and smaller atomic density. Herein, novel γ‐graphdiyne quantum dots (GD QDs) are used in perovskite solar cells as a surface modifier or dopant to TiO2, CH3NH3PbI3, and Spiro‐OMeTAD to realize multiple advantageous effects, in hoping that it would form a more effective carrier transport channel for boosted solar cell performance. First, the presence of GD QDs on TiO2 surface increases perovskite grain size for higher current density and fill factor. Second, the GD QDs at each interface reduce the conduction band offset, passivate the surface for suppressed carrier recombination to attain higher open‐circuit voltage. Third, it improves hydrophobicity and eliminates pinholes in the Spiro‐OMeTAD film for enhanced solar cell stability. As a result, the optimized device shows >15% enhancement in power conversion efficiency (from 17.17 to 19.89%) comparing to the reference device. More significantly, the device stability was improved in harsh environment (moist air, UV irradiation, or thermal conditions). It is expected that GD QDs will find their applications in efficient and stable perovskite solar cells and optoelectronic devices.

Although several sponge-like sorbents have been developed to treat oil spills and chemical leakages, under harsh conditions (e.g., strong acid or alkali; oils on the sea) their efficiencies can be rather limited. Herein, we provide a graphdiyne sponge that is capable of collecting oil pollution effectively. This graphdiyne sponge exhibits excellent adsorption capacity (up to 160 times its own weight), robust stability (even when immersed in strong acid and alkali for 7 days), and remarkable recyclability (up to 100 times). These features suggest that this new adsorbent material might find applicability in the cleanup of oil spills and many organic pollutants under realistic conditions.
