Abstract
In order to obtain better abiotic receptors for analytical and kinetic applications, the new capped derivative of cyclomaltoheptaose (CDTH) was synthesized by reaction of 6, 6’-dideoxy-6, 6’-di(S-cysteamine)-α, α’-trehalose with 6A, 6D-dideoxy-6A, 6D-diiodo-cyclo-maltoheptaose. The CDTH-ACS (anthraquinone-2-sulfonic acid sodium salt) system was investigated, by 1H NMR spectroscopy and by i.c.d. (induced circular dicroism), and a deep inclusion of ACS inside the CDTH cavity, with an association constant about six times larger with respect to ACS — β-CD system was found.
