Bifunctional azo dyes

A second method for the synthesis of organometallic polynorbomenes containing a bound azo dye involved the reaction of T -chlorotoluene- n -cyclopentadienyliion complex 21 with bifunctional azo dyes to yield the azo dye-containing organoiron compounds, which wctc then further reacted with 5-norbomene-2-carboxylic acid (16) to form the azo dye functionalized norbomene monomers, 24, shown in Scheme 7.7. 

Polymers containing both netural and cationic iron moieties have been prepared from organoiron complexes containing ferrocene and azo dyes in the main chain with pendent cationic iron units. The monomers were prepared by first reacting bifunctional azo dyes 34 with the organoiron complex (1) (Scheme 7.11).
