摘要: 二氧四胺大环和取代二氧四胺大环化合物兼有大环氮杂冠醚和低聚肽的性质,能和很多过渡金属离子(Cu2+,Ni2+,Mn2+,Co2+等)形成具有特殊功能的配合物.如十四元二氧四胺大环Co(Ⅱ)配合物在-70℃加入过量的咪唑或吡唑后.

Abstract: MCM-41 m aterials loaded with cupric complexes of 4, 8 bis(2-thienylmethyl 1, 4, 8, 11 tetraazacyclotetradecane 12, 14 dione(14T2Cu)and 1, 4, 8, 11 tet raazacyclotetradecane 12, 14 dione(140Cu)were prepared by mixing The corresponding complexes respectively with silica form of mesoporous molecular sieve MCM-41.The composite materials were characterized by powder XRD, UV-Vis and ESR spect roscopies.The absorption max imum for 14T2Cu/MCM-41 shifts towards The higher frequency by 19 nm in comparison with 14T2 Cu complex in met hanol solution, whereas The absorption for 140Cu/MCM-41 is close to that for 140Cu in methanol.Both 14T2Cu and 140Cu complexes behave anisotropicaly within The channel of MCM-41 material on the basis of ESR spectra.

Key words: Dioxotetraam ines, Mesoporous, MCM41, ESR, UV-Vis
