Highly colored organometallic thermoplastics: polymers incorporating azo dyes.

Prepn. of organoiron monomers that contain one or more azo dye functionalities was performed. It was found that the resulting organoiron complex contained multiple azo dyes functionalities. Very good yields of organoiron polymers contg. multiple dyes were obtained for the nucleophilic arom. substitution reactions of complex compd. with O- or S-contg. dinucleophiles. These materials were found to be thermally stable, and characterization of these materials displayed unique photophys. and electrochem. properties.
