Аннотация:Conclusions 1. The oxidation of lithium phthalocyanine with chloranil, bromanil, tetracyanoquinodimethane, dichlorodicyano-p-benzoquinone, and halogens leads to the formation of the stable lithium phthalocyanine radical. The latter is readily reduced to PcH 2 by mineral acids and hydroquinone. The partial oxidation of PcLi . leads to a charge-transfer complex having increased electrical conductivity. 2. On the basis of magnetic susceptibility data it was suggested that PcLi. has antiferromagnetic characteristics.
