“…N-GDY with precise molecular doping shows enhanced paramagnetism . We have anticipated that the content of pyridine nitrogen can be higher when prepared by the bottom-up molecular design method rather than the postdoping method, which enhances the local spin polarization further; meanwhile, the magnetic order in GDY is obtained. The molecularly precise doping method of nonmetallic H, F, and Cl endows graphdiyne with intrinsic magnetism, and transition metal (Fe, Co, Ni) doped graphdiyne has a low doping metal content.…”

“…Among them, the Curie temperature ( T c ) of the Co-GDY material can reach 350 K, and the H c can reach 78 Oe at 300 K, which is a good candidate for spin device materials. Fe/N codoped graphdiyne also exhibits ferromagnetism close to room temperature . Because the low doping amount has little effect on the bandgap of graphdiyne, the intrinsic semiconducting properties of graphdiyne are maintained.…”

Magnetism in low-dimensional carbon materials, which is crucial for the realization of the physical properties, potential application, and development of carbon-based spintronic devices, has attracted extensive attention. In this Review, three typical low-dimensional carbon materials, including carbon nanotubes, graphene, and graphdiyne, are used to exhibit the research progress of a magnetic two-dimensional (2D) carbon material preparation strategy, the introduction of the local magnetic moment, and the resulting unique magnetic properties. The convenient and facile preparation methods of carbon-based magnetic materials have been introduced on the basis of their structural characteristics, especially for the advantageous structures and efficient chemical modification in graphene and graphdiyne. Various interesting ways, such as transition metal atom doping and nonmetal atom modification, have been exhibited to tune the electromagnetic characteristics of carbon-based materials. All those research studies provide a theoretical basis to promote the application of 2D carbon-based magnetic materials in spintronic devices involving spin and charge modulation and lay a foundation for the preparation of high-performance carbon-based magnetic materials with specific magnetic properties.

Graphdiyne (GDY) is a carbon allotrope with an alkyne-rich framework constructed from the coupling of terminal alkynes in hexaethynylbenzene (HEB); thus, efficient acetylene–acetylene bond coupling is essential to synthesize high-quality GDY. In this work, a copper(II) trichloro catalyst (CuTC) was introduced for GDY growth in the presence of a Cu foil, N,N,N,N′-tetramethylethylenediamine (TMEDA), and trichloromethane (CHCl3) at a mild temperature. High-quality GDY sheets on a gram scale can be obtained at a yield of 42% by increasing the content of HEB and Cu foil, which forms the foundation for their further applications. A mechanistic study demonstrated that Cu–Cl bonds play an important role in the formation of the Cu(II)–diacetylide intermediate, which extended GDY growth to other benign solvents, such as dichloromethane (DCM), ethyl acetate (EA), tetrahydrofuran (THF), and N,N-dimethylformamide (DMF). Besides, GDY analogues H-GDY, COOCH3-GDY, and Py-GDY can be successfully grown on the surface of a Cu foil with a higher 1,3-diyne content than that mentioned in previous reports. GDY synthesized by the present method showed enhanced photocatalytic activity in hydrogen evolution upon hybridization with π-conjugated molecules through a π–π stacking interaction, which is powerful for constructing novel heterojunction materials by adjusting the electronic structure of GDY, thereby enhancing the light absorption ability of the system. Our work will contribute to the preparation of high-quality GDY and its analogues and extend their applications in various areas in the future.

“…At present, a vast majority of biological molecules are being used to detect and measure different targets, threatening human life and the environment. − Simplicity and sensitivity are two key features determining the applicability of these detection methods. FET biosensors, to a high extent, afford these key features, and as a result, a profound investigation of this type of biosensors can be found in the literature. ,− With GDY possessing a high carrier mobility (≈104 cm 2 V –1 s –1 ) as a p-type semiconductor with a tunable band gap, its usage in electronic devices such as FETs is getting expanded. , Also, it has been proven both theoretically and experimentally that GDY-based FETs have a great on/off ratio of over 10 4 and a considerable on-state current of 1.3 × 10 4 mA·mm –1. There is no doubt that there are many 2D materials that possess exclusive properties.…”

Graphdiyne's (GDY's) outstanding features have made it a novel 2D nanomaterial and a great candidate for electronic gadgets and optoelectronic devices, and it has opened new opportunities for the development of highly sensitive electronic and optical detection methods as well. Here, we testified a non-covalent grafting strategy in which GDY serves as a charge carrier layer and a bioaffinity substrate to immobilize biological receptors on GDY-based field-effect transistor (FET) devices. Firm non-covalent anchoring of biological molecules via pyrene groups and electrostatic interactions in addition to preserved electrical properties of GDY endows it with features of an ultrasensitive and stable detection mechanism. With emerging new forms and extending the subtypes of the already existing fatal diseases, genetic and biological knowledge demands more details. In this regard, we constructed simple yet efficient platforms using GDY-based FET devices in order to detect different kinds of biological molecules that threaten human health. The resulted data showed that the proposed non-covalent bioaffinity assays in GDY-based FET devices could be considered reliable strategies for novel label-free biosensing platforms, which still reach a high on/off ratio of over 10 4 . The limits of detection of the FET devices to detect DNA strands, the CA19-9 antigen, microRNA-155, the CA15-3 antigen, and the COVID-19 antigen were 0.2 aM, 0.04 pU mL −1 , 0.11 aM, 0.043 pU mL −1 , and 0.003 fg mL −1 , respectively, in the linear ranges of 1 aM to 1 pM, 1 pU mL −1 to 0.1 μU mL −1 , 1 aM to 1 pM, 1 pU mL −1 to 10 μU mL −1 , and 1 fg mL −1 to 10 ng mL −1 , respectively. Finally, the extraordinary performance of these label-free FET biosensors with low detection limits, high sensitivity and selectivity, capable of being miniaturized, and implantability for in vivo analysis makes them a great candidate in disease diagnostics and pointof-care testing.
