✦ Synopsis

80, CH-4056 Basel

We report on the synthesis of a receptor 4 for b,P-carotene (l), and on the binding interaction between the two which yields inclusion complex 5. The cyclodextrin 'dimer' 4 was obtained via condensation of the corresponding 4,4-(porphyrin-5,15-diyl)bis phenol 8 with 6A-dcoxy-6A-iodo-~-cyclodextrin (6) in the presence of Cs,CO,.

Fluorescence studies of the binding interaction between 'dimer' 4 and PJ-carotene (1) gave a binding constant K, O f (2.4 & 0.1). lo6 M -'
