Abstract
In this contribution we present results of photoinduced absorption and electroabsortpion spectroscopy (PIA) on a new polyacetylene (PA) blen d synthesized in dilute solutions of poly(vinylbutyral) (PVB) using ne w catalysts [1]. The results indicate that the stability at ambient co nditions is enhanced and that the intrinsic long lived photoexcitation s of PA are neutral with the charged excitations becoming observable o nly after aging the material. Measurements are made both on dilute sol utions and films. The results are discussed in terms of morphology rel ated stability.
