手性反式环己二醇双芘酯(1R,2R)-1a和(1S,2S)-1b可逆还原为相应的双自由基阴离子1a2 -和1b2 -,在510 nm处表现出强吸收带,表现出相反的激子分裂圆二色性(CD),而双酰胺的自由基阴离子2a和2b则没有表现出分裂CD信号。
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.
