HETEROATOM-FUNCTIONALIZED PORPHYRAZINES AND MULTIMETALLIC COMPLEXES AND POLYMERS DERIVED THEREFROM

WIPO Patent Application WO1999012929

A3

Porphyrazine compounds having moieties substituted at the eight peripheral beta -pyrrole positions are disclosed. The porphyrazine compounds have general structural formula (V), wherein M is H2 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.
