Construction of synthetic macrocyclic host that can bind with neutral molecules and anions has potential applications in supramolecular chemistry. Herein, we have designed and synthesized blue light emitting an unsymmetrical neutral bis-urea macrocyclic host. This macrocycle can bind with neutral DMF molecule (1:1) as well as Cl⁻ ion (1:1) through noncovalent interactions. X-Ray crystal structure, ¹H NMR titrations with Job's Plot, HRMS with isotropic distribution pattern, FT-IR, and density functional theory analysis revealed the binding of bis-urea macrocyclic host with the guest molecule.

中性分子和氯离子结合的不对称双脲大环主体的构建

可与中性分子和阴离子结合的合成大环主体的构建在超分子化学中具有潜在的应用。在此，我们设计并合成了发出不对称中性双脲大环主体的蓝光。该大环可以通过非共价相互作用与中性 DMF 分子 (1:1) 以及 Cl ^-离子 (1:1) 结合。X 射线晶体结构、具有乔布图的¹ H NMR 滴定、具有各向同性分布模式的 HRMS、FT-IR 和密度泛函理论分析揭示了双脲大环主体与客体分子的结合。
