FIGURE 5.4 Structure of cycloinulohexaose and D-fructose dianhydride, the most common cyclic fructosans derived from inulin. 

Fluorescence characteristics of the products were studied in relationship to complexing activity, and the 2- and the 6-derivatives can be used as fluorescence sensors. Treatment of p-cyclodextrin with the disulfonyl chloride 24 gave capped derivatives linked through 0-6 of the AD rings or AC rings in the ratio 76 24. Yields were low, but the products are potential hosts for photo-induced electron transfer reactions. In related work cycloinulohexaose was capped by use of diphenyl-4,4 -disulfonyl chloride through 0-6 of the A-C related units. This allowed displacement reactions and, for example, phenylthio-derivatives could be made in the AC relationship. ...
