Developing materials capable of converting high-energy photons into visible (vis) or ultraviolet (UV) light serves as an effective approach for achieving X-ray detection and imaging. In this work, highly luminescent metal-organic gel (MOG), YTU-G-1, was obtained by self-assembling the aggregation-induced emission luminogen (AIEgen)-functionalized ligand and Zr oxo-hydroxy clusters via a mild solvothermal method. The dense and rigid MOG skeleton offers the opportunity to maximize the AIE effect, achieving near-unity quantum efficiency of 95.5%. Under X-ray irradiation, YTU-G-1 exhibits bright luminescence and can detect low-dose radiation down to 44 nGy s⁻¹. The robust Zr–O bond imparts the material with excellent chemical and physical resistance, making it an ideal candidate for fabricating large-area flexible membranes. Consequently, the spatial imaging resolution of the flexible scintillating membrane reaches 20 lp mm⁻¹. This work offers a general strategy for fabricating scintillators based on MOGs and facilitates the construction of flexible X-ray imaging membranes.

开发能够将高能光子转化为可见光 (vis) 或紫外 (UV) 光的材料是实现 X 射线检测和成像的有效方法。在这项工作中，高发光金属有机凝胶（MOG）YTU-G-1是通过温和溶剂热方法自组装聚集诱导发射发光体（AIEgen）功能化配体和Zr氧代羟基簇而获得的。致密且刚性的 MOG 骨架提供了最大化 AIE 效应的机会，实现近乎一致的 95.5% 量子效率。在X射线照射下，YTU-G-1表现出明亮的发光，可以检测低至44 nGy s ^-1的低剂量辐射。坚固的 Zr-O 键赋予该材料优异的化学和物理耐受性，使其成为制造大面积柔性膜的理想选择。因此，柔性闪烁膜的空间成像分辨率达到20 lp mm ^-1。这项工作为制造基于 MOG 的闪烁体提供了总体策略，并促进了柔性 X 射线成像膜的构建。
