Chiang, S.-H.; Becker, WG; Greenberg, DP J. Chem. SOC., Chem. Commun. 1980, 681. El12 (red) values were obtained by cyclic voltammetry using platinum working and auxiliary electrodes vs a saturated calomel electrode and were referenced to ferrocene/ferrocenium couple at 0.31 V vs SCE. E0. 0 values correspond to the energy at the intersection of the excitation and emission spectra (see supplementary material).(15) Yields were ...
