Suppressing the photoelectric response of organic semiconductors (OSs) is of great significance for improving the operational stability of organic field‐effect transistors (OFETs) in light environments, but it is quite challenging because of the great difficulty in precisely modulating exciton dynamics. In this work, photostable OFETs are demonstrated by designing the micro‐structure of OSs and introducing...
Tailoring the interface between organic semiconductor (OSC) and ferromagnetic (FM) electrodes, that is, the spinterface, offers a promising way to manipulate and optimize the magnetoresistance (MR) ratio of the organic spin valve (OSV) devices. However, the non‐destructive in situ regulation method of spinterface is seldom reported, limiting its theoretical research and further application in organic...
Organic semiconductor single crystals (OSSCs) are ideal materials for studying the intrinsic properties of organic semiconductors (OSCs) and constructing high‐performance organic field‐effect transistors (OFETs). However, there is no general method to rapidly prepare thickness‐controllable and uniform single crystals for various OSCs. Here, inspired by the recrystallization (a spontaneous morphological...
2D materials are increasingly becoming key components in modern electronics because of their prominent electronic and optoelectronic properties. The central and premise to the entire discipline of 2D materials lie in the high‐quality and scaled preparations. The chemical vapor deposition (CVD) method offers compelling benefits in terms of scalability and controllability in shaping large‐area and high‐quality...

Nanospheres lithography (NSL) is an economical technique, which makes use of highly monodispersed nanospheres such as deposition or etch masks for generating patterns with nanoscale features. Embedding nanostructures into organic electronic devices can endow them with unique capabilities and enhanced performance, which have greatly advanced the development of organic electronics. In this review, a...
There is very limited repertoire of organic ambipolar semiconductors to date. Electron donor–acceptor alternative stacking is a unique and important binary motif for 1D mixed‐stack cocrystals, opening up possibilities for the development of organic ambipolar semiconductors. Herein, four 1D mixed‐stack cocrystals using N,N′‐bis(perfluorobutyl)‐1,7‐dicyanoperylene‐3,4:9,10‐bis(dicarboximide) (PDICNF)...
Copper tetracyanoquinodimethane (CuTCNQ) has been investigated around 40 years as a representative bistable material. Meanwhile, micro/nanostructures of CuTCNQ is considered as the prototype of molecular electronics, which have attracted the world's attention and shown great potential applications in nanoelectronics. In this review, methods for synthesis of CuTCNQ micro/nanostructures are first summarized...
Electrochemical CO2 reduction (ECR) to value‐added chemicals and fuels is regarded as an effective strategy to mitigate climate change caused by CO2 from excess consumption of fossil fuels. To achieve CO2 conversion with high faradaic efficiency, low overpotential, and excellent product selectivity, rational design and synthesis of efficient electrocatalysts is of significant importance, which dominates...
Ambipolar organic field‐effect transistors (OFETs) are vital for the construction of high‐performance all‐organic digital circuits. The bilayer p–n junction structure, which is composed of separate layers of p‐ and n‐type organic semiconductors, is considered a promising way to realize well‐balanced ambipolar charge transport. However, this approach suffers from severely reduced mobility due to the...
On account of unique characteristics, the integration of metal–organic frameworks as active materials in electronic devices attracts more and more attention. The film thickness, uniformity, area, and roughness are all fatal factors limiting the development of electrical and optoelectronic applications. However, research focused on ultrathin free‐standing films is in its infancy. Herein, a new method,...
Following the development of photoluminescence systems with various compositions, some nontraditional structures, including nonaromatic organic systems as fluorophores and organic luminogens as the source of phosphorescence emission at room temperature, have attracted considerable attention for their advantages in biological and medical applications, and for the updated photophysical understandings...
Synthesizing ultrathin 2D metal–organic framework nanosheets in high yields has received increasing research interest but remains a great challenge. In this work, ultrathin zirconium‐porphyrinic metal–organic framework (MOF) nanosheets with thickness down to ≈1.5 nm are synthesized through a pseudoassembly–disassembly strategy. Owing to the their unique properties originating from their ultrathin...
Direct growth of chirality‐controlled single‐walled carbon nanotubes (SWNTs) with metal catalyst free strategy, like cloning or epitaxial growth, has suffered from the low efficiency.
