    • Since the LUMO energy level is a good guide for the ability of electron acceptors, LUMO energy levels of these weak electron acceptors were estimated with semi-empirical MO calculation (PM3: 2,4,6-tribromoanisole, -0.72 eV; 4-nitroanisole, -1.08; N-methyl-3-nitrophthalimide, -1.78; N-methyl-4-nitrophthalimide, -2.09).
