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.展开更多
