AI Article Synopsis
- Solution-processed organic single crystals are being studied for uses in displays, sensors, and flexible electronics, but issues with alignment and growth control limit their industrial use.
- A new method involving photochemical modification and vapor annealing has been developed to create high-performance organic single-crystal thin film transistors with impressive mobility and multiple aligned crystals.
- The research also examines the mechanical properties of these organic single crystals under extreme bending conditions, with a bending radius of 150 μm.
Article Abstract
Solution-processed organic single crystals with high carrier mobility have been actively investigated for diverse applications such as displays, sensors, and next generation electronics on a flexible platform. However, the lack of precise alignment and growth control of organic single crystals impedes the widespread adoption of organic materials in an industrial perspective. Here, a photochemical modification approach is reported tailoring the solubility and molecular diffusivity of polymeric sacrificial layer and sequential batch-type vapor annealing to implement high-performance (average saturation mobility: 8.01 cm V s ) organic single-crystal thin film transistors with large channel width including multiple aligned single crystals. Additionally, the mechanical properties of the organic single crystals are systematically investigated with extreme strain conditions such as bending radius of 150 μm.

In the search for novel natural products with hepatoprotective effects against acetaminophen-induced acute liver injury, the marine-derived fungus WHUF0198 was investigated. Seventeen undescribed pyranopyridone alkaloids, aculeapyridones A-Q (-), were isolated by bioactivity-guided fractionation of an extract obtained by coculture of the WHUF0198 with the mangrove-associated fungus sp.

The photoinduced reaction of [Pt(NO)] with pyridine or its derivatives (L) was found to result in the formation of [PtL](NO) salts in high yield. This transformation was successfully probed for methyl- and carboxyethyl-substituted pyridines, and the corresponding [PtL](NO) salts were isolated and fully characterized using single-crystal X-ray diffraction (SCXRD). Anation of the [Pt(py)] cationic complex with N was studied by H NMR spectroscopy in aqueous and water/dimethyl sulfoxide solutions of [Pt(py)](NO).

Achieving multicolor emission is a fascinating goal that remains challenging for zero-dimensional (0D) hybrid halides. We successfully obtained a three-millimeter-scale 0D (MXDA)CdBr (MXDA = CHN) single crystal (SC) by the solvothermal method. It serves as an outstanding host for doping with various valence activators, such as Cu, Mn and Sb, and these doped single crystals emit blue (470 nm), yellow (580 nm) and red (618 nm) fluorescence, which accurately cover a large visible region and achieve efficient multicolor emission.
