摘要：

Double integration of the electron paramagnetic resonance signal associated with the green form of lutetium bisphthalocyanine in dimethylformamide solution indicates it is a minor species. Magnetic circular dichroism spectroscopy strongly suggests the chromophore is not a radical. These findings are in keeping with the recently resurrected hypothesis [Daniels et at, J. Coord. Chem. (1993) 28, 23-31] that the ''electrochromic'' color changes observed in lanthanide bisphthalocyanine chemistry are acid-base in nature and not due to oxidation-reduction processes involving the phthalocyanine rings.
