Phosphorus Copies of PPV
We have developed the first π-conjugated polymers containing a multiple bond involving phosphorus in the main chain (PPP). Detailed studies of the electronic properties of PPPs and their model compounds revealed that there is considerable π-conjugation in these polymers. Significantly, the trans-PPP (Z-PPP) exhibits the highest degree of conjugation. This significant breakthrough may pave the way for possible applications in the area of electronic materials.
