摘　　要：By introducing a host molecule cucurbit[8]uril(CB[8]) into a charge transfer system containing an amphiphile 1-[11-(naphthalene-2-ylmethoxy)-11-oxoundecyl]pyridinium(NP) and an electron-deficient molecule methyl viologen(MV), a novel and anisotropic ternary building block was constructed by hostguest interactions, thereby leading to the morphology transformation of the final assemblies from thinfilms(NP/MV complexes) into diamond-like structures(NP/MV/CB[8] complexes). These intriguing assemblies were firstly discovered and were similar with the shape of well-known metal organic frameworks(MOFs), but just comprised three small organic molecules without metal ions. This finding can enrich the shape of current supramolecular assemblies and thus contributing to more potential applications in material science.
