中文摘要：

复合、相应的锌(II ) porphyrin-salen 化合物(ZnPSC10 ) covalently 由灵活 alkoxy 链(O (CH ) 10O ) 连接了的新奇 porphyrin-salen 被综合了并且描绘。三个 N 杂环的客人的分子的识别， pyridine， 1,4-diazobycyclo [2,2,2 ] 辛烷(DABCO ) 和 pyrazine，与主人， ZnPSC10 被调查。有约束力的常数借助于紫外力的滴定方法被决定。有 DABCO 的 ZnPSC10 的有约束力的模式被使用 1H NMR 详细讨论了。识别系统的符合构造变化了从，这被发现关门了与增加 DABCO 开。

英文摘要：

A novel porphyrin-salen compound and corresponding zinc（Ⅱ） porphyrin-salen compound （ZnPSC10） covalently linked by a flexible alkoxy chain （-O（CH）10O--） have been synthesized and characterized. Molecular recognition of three N-heterocyclic guests, pyridine, 1,4-diazobycyclo[2,2,2]octane （DABCO） and pyrazine, with the host ZnPSC10 was investigated. Binding constants were determined by means of UV-vis titration method. The binding mode of ZnPSC10 with DABCO has been discussed in detail by using ^1H NMR. It was found that the conformations of the recognition system changed from closed to open with the adding of DABCO.
