Role of Oxygen in the Redox Chemistry of Lutetium Diphthalocyanine

摘要

Spectroscopic evidence on the role of oxygen in the redox chemistry of lutetium diphthalocyanine is reported. The observations indicate an irreversible reaction of oxygen with vacuum-sublimed films of the dye material and a reversible reaction with its solution in dimethylformamide. This behavior can account for several apparent anomalies found in previous investigations.
