Abstract

Formyl-substituted chromenone receptors have been prepared and their self-association process were studied in chloroform solutions. The structure of the aggregates depends on the configuration of the formyl group. The Z/E ratio dependence with the molar concentration and X-Ray crystallographic data is used to discuss the structure of the associates.
