Abstract
beta-Cyclodextrin derivative 1, bearing a group with two pyrene moieti es, exhibits predominant excimer emission in a 20% DMSO aqueous soluti on. In spite of the fact that pyrene is too large to be included in th e beta-cyclodextrin cavity and consequently both pyrene moieties are l ocated outside the cavity, 1 varies the excimer emission intensity thr ough the formation of inclusion complexes with guest species, thus act ing as a chemosensor for molecular recognition.
