high-fidelity and self-complementary halogen bonding moiety, 2-iodooxazole, was identified using density functional theory-based calculations. Installation of 2-iodooxazole on two geometrically complementary cores using a two-step synthetic approach gave the tectons 1,4-bis(2-iodooxazol-5-yl)benzene (BIOx) and 1,4-bis(2-iodooxazol-5-yl)-2,3,5,6-tetrafluorobenzene (FIOx).

使用基于密度泛函理论的计算鉴定出高保真且自互补的卤素键合部分 2-碘恶唑。使用两步合成方法将 2-碘恶唑安装在两个几何互补的核心上,得到构造 1,4-双(2-碘恶唑-5-基)苯 (BIOx) 和 1,4-双(2-碘恶唑-5 ) -基)-2,3,5,6-四氟苯 ( FIOx )。单晶 X 射线衍射研究表明BIOx和FLOx具有组装成结晶、多维卤素键合网络所需的强度和几何形状。通过化学直观的溶剂条件控制组装允许一维、二维或三维卤素键合网络的有意组装。这项工作表明,通过仔细设计构造和晶体生长条件,卤素键合网络可以满足氢键类似物设定的标准。
