Abstract

Upon electrochemical oxidation of configurationally stable (M)-4, 5-dimethyl-9, 10-dihydrophenanthrene attached with two spiroacridan units at the C9 and C10 positions [(M)-1c], a threeway-output response by UVvis, FL, and CD spectra was realized via clean conversion to the corresponding bond-dissociated dication (Rax)-2c2+. Similar gradual changes were induced upon standing of an aerated MeCN solution of (M)-1c after the addition of CF3CO2H because the elongated C9C10 bond was also cleaved by oxidative protonolysis to give (Rax)-2c2+.
