1H NMR study of the inclusion of Costa-type organocobalt(III) complexes in cyclodextrins.
The inclusion behavior between Costa-type complexes and cyclodextrins (CDs) was studied by 1H NMR in aqueous solution. The results indicated that 1:1 inclusion complex was formed, in which the alkyl group of the guest was included in the cavity of CDs. The stability constants of the inclusion complexes were determined by the quantitative 1H NMR method. The effects on stability constants were discussed when various host and guest compounds were used.
