Polymers with polynuclear aromatic rings

Anthracene is one of the most thoroughly studied photoconductors, and numerous attempts have been made to synthesize high-molecular-weight materials or polymers containing similar groups. Poly(9-vinyl-anthracene) [66], poly(l-vinylanthracene) and poly(2-vinylanthracene) 

Poly(vinylpyrene) [71, 72] (and D.M. Pai, personal communication) is also UV-photoconductive, with hole mobility at room temperature and = 2xlO Vm around 7.5 X Similarly, UV- 

Several other polymers with large pendant groups, such as poly-(9-vinylacridine) [74], also display some degree of photoconductivity. 

The patent literature details many photoconductive resins made by polycondensation of aromatic compounds with formaldehyde and the like, but, typically, no fundamental measurements of charge generation or transport have been made.
