Here, we report the synthesis of adamantane-based macrocycle by combining adamantane building blocks with π-donor 1,3-dimethoxy-benzene units. An unpredictable keto-adamantane-based macrocycle was obtained by the oxidation of using DDQ as an oxidant. Moreover, a new type of macrocyclic molecule-based CT cocrystal was prepared through exo-wall CT interactions between and DDQ. The cocrystal material showed selective vapochromism behavior towards THF, specifically, among nine volatile organic solvents commonly used in the laboratory. Powder X-ray diffraction; UV-Vis diffuse reflectance spectroscopy; H NMR; and single crystal X-ray diffraction analyses revealed that color changes are attributed to the vapor-triggered decomplexation of cocrystals.
在此，我们报告了通过将金刚烷构建单元与π供体1,3-二甲氧基苯单元相结合来合成基于金刚烷的大环化合物。使用DDQ作为氧化剂对其进行氧化，得到了一种不可预测的基于酮基金刚烷的大环化合物。此外，通过[大环化合物]与DDQ之间的外壁电荷转移相互作用制备了一种新型的基于大环分子的电荷转移共晶体。该共晶体材料对四氢呋喃表现出选择性气致变色行为，具体而言，在实验室常用的九种挥发性有机溶剂中表现出这种特性。粉末X射线衍射、紫外-可见漫反射光谱、核磁共振氢谱和单晶X射线衍射分析表明，颜色变化归因于共晶体的蒸汽触发解络合作用。
