Abstract
The chiral trans-cyclohexanediol bispyrene esters (1R,2R)-1a and (1S,2S)-1b are reversibly reduced to the corresponding bisradical anions 1a2– and 1b2– which show strong absorption bands at 510 nm exhibiting exciton-split circular dichroism (CD) with opposite signs, whereas the radical anions of the bisamides 2a and 2b failed to show split CD signals.Keywords
