The present study demonstrates the use of triazole moiety in designing molecules endowed with the ability for self-assembly and molecular recognition. The receptors 7a and 9a having open structures bind to fluoride ion with good affinity. Various cyclophanes with 19-, 20-, 21-, 38-, and 40-membered rings containing triazole units were designed and synthesized. X-ray crystal structure of macrocycle
本研究证明了三唑部分在设计具有自组装和分子识别能力的分子中的用途。具有开放结构的受体7a和9a以良好的亲和力与氟离子结合。设计并合成了具有19、20、21、38和40元环的含有三唑单元的各种环烷。大环16的X射线晶体结构显示为管状结构。三唑烷22具有分叉的CH⋯N分子内氢键,并通过CH⋯N相互作用以固态形式进一步组织。三唑类化合物是利用CH = O和CH = N氢键相互作用进行分子自组装的潜在仓库。
