Abstract

A new fluorescent sensor based on a dimethylxanthene skeleton has beensynthesized. Because of its oxyanion hole structure, this receptor includes a suitablecavity for the association of carboxylic acids. The receptor’s fluorescence is quenchedupon addition of dinitrobenzoic acid.
Keywords: Dimethylxanthene; fluorescent sensor; molecular recognition; carboxylic acid receptor; oxyanion hole. Dimethylxanthene; fluorescent sensor; molecular recognition; carboxylic acid receptor; oxyanion hole.
