【 摘 要 】

Metallosupramolecules self-assembled by a discrete number of molecules attract attention due to their fascinating structural features as well as potential applications in catalysis, gas storage and separation, molecular magnets, and molecular devices.1−6 Non-covalent intermolecular interactions such as hydrogen bonds, π-π interactions and CH…π interactions in addition to metal-ligand covalent bonds are frequently observed in the process of selfassembling discrete molecules to form large supramolecular structures.7−11 Among various metallomacrocycles, the complexes of a macrocycle L (L = 3,10-bis(3-(2-methyl1-imidazolyl)propyl)-1,3,5,8,10,12-hexaazacyclotetradecane) bearing two imidazole pendants on the macrocycle are of special interest owing to their favorable structural features for the formation of metallosupramolecules. The imidazole pendants on L are expected to participate in intermolecular interactions as hydrogen bond donors and/ or acceptors. The involvement of C-H…π interactions and π-π interactions between the imidazole pendants are another type of intermolecular forces to be anticipated in the self-assembly process of metallomacrocycles with L. With the structural advantages of L described above in mind for the assembling metallosupramolecules, we attempted and successfully self-assembled the nickel(II) complexes of macrocycle L.
