[GRAPHICS]A series of permethylated cyclodextrin derivatives, cyclodextrin dimers doubly bridged with two anthracene moieties ( An(2)CD(2)) and singly bridged with one ( AnCD(2)) and the monomer bearing two anthracene moieties ( An(2)CD), were newly synthesized. For An(2)CD(2), the two isomeric forms are also identified. All compounds are soluble in both aqueous and various organic solvents. The bisanthracene systems, An(2)CD(2) and An(2)CD, show the thermal equilibrium in an aqueous solution between the intramolecularly interacting ( closed) and less-interacting ( open) states of the anthracene moieties, which results in the temperature-dependent absorption changes. These systems also show the characteristic excimer emission that is enhanced in water and weakened in organic solvents. The excitation spectra for the monomer and excimer fluorescence are found to be quite different from each other and similar to the absorption spectra of the open and the closed forms, respectively. The observed unique parallelism between excitation and absorption spectra for the present excimer systems indicates the dual ground state-dual excitation scheme where the excitation state formed from the closed ground state mainly gives excimer. The fluorescence lifetime analyses reveal that the rates of the conversion from the excited state of the open form to that of the closed one ( 6.0 x 10(6) s(-1) for An(2)CD(2)-2) are largely retarded compared with that of the ethyleneoxy linked bisanthracene system ( 8.8 x 10(7) s(-1)).

Des ethylenedioxydiethylenes dioxadiaza [14]- et [16] anthracenophanes (A) sont etudies. Les electrons non apparies de l'azote forment avec le noyau anthracene des exciplexes intramoleculaires. Ces composes (A) donnent lieu a une emission de fluorescence (de type monomere et exciplexe) sensible a la nature protique ou aprotique du solvant. Les cryptates sont egalement etudies
