This paper summarizes the main research of azacrown ether compounds and macrocyclic polyamines in our group from 1985 to 2000. It consists four parts: (1) Research of synthetic method of a series new macrocyclic compounds: benzoazacrown ether, azacrown ethers containing central functional group and their N-pivot lariat derivatives, Schiff's azacrown ethers and macrocyclic polyamines containing pyridine or bipyridine ring etc. (2) Application of NMR in the complexation of N-substituted benzocrown ethers with p-toluene diazonium fluoroborate, conformation of azacrown ether containing central group, and research of dilution shift effect. (3) Research of synthesis and photochromism of crowned indolinospiropyrans as artifical signaling recepter. (4) Synthesis and molecular recognition of cyclodextrin dimers.
