Particularly, their distinctive structural characteristics offer promising prospects for suppressing ion migration, which is highly advantageous for X-ray detection. Herein, by gradually modifying the cyclohexylmethylamine cation into the 4-aminomethyltetrahydropyran cation, a layered heterostructure single crystal (PbCl<sub>2</sub>)<sub>2</sub>(4-Aminomethyltetrahydropyran)<sub>2</sub>PbCl<sub>4</sub> is successfully obtained. It comprises two distinct inorganic frameworks, namely a perovskite layer built from PbCl₆ octahedra and an intergrowth layer consisting of PbCl₂ units, wherein the organic components are Advanced science (Weinheim, Baden-Wurttemberg, Germany)Suppressing Ion Migration in Heterostructure Single Crystals for Highly Sensitive Ultra-Stable X-Ray Detection.PMC124629732022TQ03372024M7532332023M7334972024T17092322125110GZB2024074622305248U23A2094U21A20692023J02028Li WLiu YTang LLuo JGuo WMa YXu HFan QWei LSun ZfalseSuppressing Ion Migration in Heterostructure Single Crystals for Highly Sensitive Ultra-Stable X-Ray Detection.Heterostructure single crystals have emerged as a significant functional material system due to their unique properties and potential for novel optoelectronic device applications.
