Supramolecular organic frameworks (SOFs) made of organic guest molecule and cucurbit[8]uril (CB[8]) in aqueous solution have great potential for diverse applications. Herein, we designed highly fluorescent zero-dimensional (0D) nano-ring SOF with CB[8] as a host and novel bent-shaped cyanostilbene guest. This host-guest complex successfully formed macrocyclic hexamer and showed significantly enhanced fluorescence (Φ =68 %) compared to non-assembled monomer (Φ =2 %). Unlike other SOFs, this 0D SOF could be dispersed uniformly without bundling phenomenon in water.
由有机客体分子和葫芦[8]脲（CB[8]）在水溶液中形成的超分子有机框架（SOFs）在多种应用中具有巨大潜力。在此，我们设计了以CB[8]为主体、新型弯曲状氰基芪客体的高荧光零维（0D）纳米环SOF。这种主客体复合物成功形成了大环六聚体，与未组装的单体相比，荧光显著增强（Φ = 68%）（未组装单体的Φ = 2%）。与其他SOFs不同，这种0D SOF在水中可以均匀分散而无聚集现象。
