Abstract:

The molecular recognition abilities of β-naphthoated β-CD derivatives as the host compounds were studied: 3-o-β-Naphthoyl-β-CD has a largely improved association constant with cyclohexanol than the corresponding 6-position substituted β-CD derivative has. On the other hand, the polarisablity and the sturcture of the gueset molecule are also important factors which affect the association constant. Cyclohexane may form the 1:2 type inclusion compound with the host compound in this report.

Key words: β-Naphthoated β-CD derivatives, Host-Guest chemistry, Molecular recognition, Difference ultraviolet spectrum
