Tetraazaporphyrins of the formula
in which
L , L , L and L , independently of one another, are the radical of a bicyclic, aromatic heterocyclic ring having 1 to 3 identical or different hetero atoms, selected from the group comprising N, O and S, which is optionally substituted, and
R and R are each as defined in the description,
and an optical recording medium containing the novel tetraazaporphyrins. |
