Soluble Polystyrene (PS) - PPP diblock and PS-PPP-PS triblock copolymers were synthesized by aromatization of the corresponding PS - poly 1,3 cyclohexadiene precursors. For a given PS sequence, the degree of agregation of these copolymers in solution increases with the length of PPP sequences. The sizes of PPP microdomains in the core of these micelles were determined. Spectral characterization of n and p doping of these solutions are presented.
