Carboxylic acid group pendent poly(p-phenylene vinylene) was synthesized and its layer-by-layer film with poly(ethylene imine) was fabricated by means of self assembly technique. The photoluminscence efficiency of the PPV-COOH in solution increases as increasing pH and the size of counter cation. The photoluminescent spectrum of the self-assembled PPV-COOH film is red shifted by ca. 10 nm compared to that of the casted film.
