兰州大学化学与化学工程学院丁三元研究团队研制了共价有机多环的设计合成。2025年2月10日出版的《美国化学会杂志》发表了这项成果。

通过刚性三臂y形和u形构件的共价组装，设计并合成了共价有机多环。这些COMs具有精确的三环结构，在一系列常见溶剂中表现出显著的溶解性。这些COMs具有明确的空腔和富电子结构，对碘在蒸汽和液体状态下都表现出良好的吸附能力。

此外，溶液可加工性允许通过自旋涂层方法在不同基材上方便地制造这些COMs作为均匀薄膜。

Abstract: Covalent organic multicycles (COMs) have been designed and synthesized via the covalent assembly of rigid three-arm Y-shaped and U-shaped building blocks. These COMs have a precise tricyclic structure and exhibit remarkable solubility in a range of common solvents. Featuring well-defined cavities with electron-rich structures, these COMs displayed good adsorption capabilities for iodine in both its vapor and liquid states. Moreover, the solution processability allows for the facile fabrication of these COMs as uniform films on different substrates via the spin coating methods.
