Summary: Organic semiconductors in optoelectronic applications require single-crystalline structures with long-range order and suppressed defects for efficient carrier transport and long photocarrier lifetime. A capillary-bridge lithography technique has been developed to control the confined crystallization of organic 1D single-crystalline arrays, achieving aligned positioning and pure orientation. The research demonstrates stable performance of organic 1D array photodetectors and successful fabrication of 20 x 20 multiplexed image sensors.

Summary: Although most recently developed molecular ferroelectrics (MFs) have excellent ferroelectric properties, their practical applications are hindered by limited polarization axes, poor processing capability for high-quality thin films, and incompatibility with matured lithography techniques for microelectronics. This study successfully demonstrates a lithography-compatible, solution-processed strategy called dewetting-assisted patterning crystallization strategy, which can overcome the above-mentioned obstacles. Using this strategy, uniform and well-aligned single-crystalline thin-film arrays of multiaxial MF [3-oxoquinuclidinium]ClO4 ([3-O-Q]ClO4) are prepared. The obtained single-crystalline nonvolatile memory (NVM) arrays exhibit ultralow operating voltage and long endurance cycles, surpassing other organic NVM devices. This work suggests a promising approach for high-density single-crystalline memory arrays for data storage, especially for low-cost flexible electronics.

Summary: This study prepared a series of MOF-based derivatives using suitable methods and evaluated their electrochemical performance. It was found that phosphating treatment can enhance the material's electrical conductivity, while the layered structure facilitates the intercalation/deintercalation of electrolyte ions, and oxidation inhibits the release of electrochemical performance. Therefore, the enhancement effect in terms of electrochemical performance is ranked as follows: phosphorization > layer structure > oxidation. This study provides reliable criteria for the design and screening of advanced electrode materials.

Summary: Fabrication of single-crystalline organic semiconductor patterns is challenging due to the uncontrollable nucleation locations and anisotropic nature. A vapor growth protocol is presented in this study to achieve patterned organic semiconductor single-crystals with high crystallinity and uniform crystallographic orientation. The protocol involves microspacing in-air sublimation and surface wettability treatment to precisely pin the organic molecules and induce homogeneous crystallographic orientation. The developed protocols enable the alignment of anisotropic electronic nature of single-crystal patterns in large-scale devices integration.

Summary: This study successfully demonstrated a rapid synthetic method for crystalline CTFs and revealed their polymerization mechanism. Photocatalytic studies with CTFs of different crystallinity showed that large crystalline domains can significantly enhance catalytic performance. Moreover, single-layer and few-layer crystalline 2D triazine polymer nanosheets can be obtained through simple ball-milling exfoliation, leading to nearly fivefold improvement in photocatalytic hydrogen evolution rate.
