| 摘 要： | A novel porphyrin-salen compound and corresponding zinc(Ⅱ)porphyrin-salen compound(ZnPSC_(10))cova-lently linked by a flexible alkoxy chain(—O(CH)_(10)O—)have been synthesized and characterized.Molecular rec-ognition of three N-heterocyclic guests,pyridine,1,4-diazobycyclo[2,2,2]octane(DABCO)and pyrazine,with thehost ZnPSC_(10)was investigated.Binding constants were determined by means of UV-vis titration method.Thebinding mode of ZnPSC_(10)with DABCO has been discussed in detail by using ~1H NMR.It was found that the con-formations of the recognition system changed from closed to open with the adding of DABCO.

| Abstract: | 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. |
