摘要：

The host-guest complexation behaviour of beta -cyclodextrin 6-O-mono-2-naphthoate (1) and 6-[(N-2-naphthoyl-2-aminoethyl) amino]-6-deoxy-beta -cyclodextrin (2) have been studied by the circular dichroism method. The exciton coupling band of 1 suggests that two naphthoyl moieties are partly included in one beta -CD cavity. Host 1 could form a dimer in a more polar solvent and the dimer could be dissociated in a less polar solvent or by adding a guest. Solvent-induced, concentration induced, and guest-induced circular dichroism variations were examined. No exciton coupling was observed for host 2.
