Monofunctionalized β-Cyclodextrins were coupled to calixarene derivatives bearing different fluorophores to give fluorescent cyclodextrin-calixarene couples. The cyclodextrin-calixarene couple 1 was investigated as a sensing molecule for the detection of several organic analytes in aqueous solution. Inclusion of a guest into the fluorescent sensing molecule leads to a decrease in fluorescence intensity. Compound 1 shows selectivity for organic analytes of a certain length. The fluorescent sensing molecules 2–6 were synthesized in order to investigate the influence of the different parts of the molecules on the sensing properties.
