英文摘要	A novel strapped porphyrin receptor Znl. In which two electron-rich bis(p-phenylene)-34-crown ether- 1O units are incorporated.has been designed and synthesized from the newly developed intermediate 7 for investigating new chemistry of molecular recognition. ~1H NMR and UV-Vis studies revealed that Znl displays relalively weak binding abilities to neutral electron deficient naphthalene-1,8,4.5-tetracarboxydiimide (NDI) derivatives 13 (no simple complexing stoichiometry was observed). 19 (Ka=48(±5) M-l) and 30 (Ka=46(±=5) M-1) in chloroform-d. strong binding ability to pyridine derivative 25. (Ka= 1.5(±O.12)X 10~3 M-1) in chloroform, moderately strong binding ability to tetroacationic compound 35.4PF^6 (Ka=475(±50) M-1) in acetone-d6. and very strong binding affinity to compound 22 Ka=6.5(±O.7)XIO~s M-1). Which consists of one pyridine and two NDI units. In chloroform. Remarkable cooperative effect of the intermolecular metal-ligand coordination and donor-acceptor interactions in complex Znl.22 was observed by comparing the complexing behavion between Znl and the appropriately designed guests. Complex Znl.22 possesses an unique three-dimeosional Ri-site binding fealure. For comparison, the complexing affinity of 1 toward componnds 13. 19. and 30 in chloroform-d and 35.4PF6 in acetone-de has also been investigated and the binding patterns in different complexes were explored. The results demonstrate that strapped porphyrin derivatives are ideal precursors for constructing new generation of three-dimensional multi-site artificial receptors for molecular recognition and host- guest chemistry.
