ABSTRACT:
Porphyrazine compounds having moieties substituted at the eight peripheral .beta.-pyrrole positions are disclosed. The porphyrazine compounds have the general structural formula: ##STR1## wherein M is H.sub.2 or a metal capable of complexing with the pyrrole nitrogen atoms, and A, B, C, and D are independently selected from the group consisting of a thio moiety, an amino moiety, an oxo moiety, a phospho moiety, a seleno moiety, a telluro moiety and a noncoordinating moiety, like a hydrocarbon moiety, with the proviso that not all of A, B, C, and D are a thio moiety and that not all of A, B, C, and D are a hydrocarbon moiety. The porphyrazine compounds, depending on the identity of A, B, C, and D, are capable of complexing one to four metal ions to the periphery of the porphyrazine to form a multimetallic porphyrazine. Multimetallic porphyrazine compounds can be linked peripherally to form a linear, i.e., ribbon, polymer or a two-dimension, i.e., sheet polymer. The porphyrazine compounds, and the multimetallic complexes and polymers derived therefrom, are useful in, or as, magnet materials, molecular metal conductors, pharmaceuticals, imaging agents, and dyes.
