Paper Abstract

The result of experimental studies of Photoluminescence (PL) in cis-transoid and trans-cisoid polyphenylacetylene were presented. The samples were prepared by a. newly-developed method using rare-earth metal catalyst. In contrast to polyacetylenea, the obtained PPA samples were soluble in common organic solvents and can be proceaaed into thin film. Comparing the results of diferent form of samples: powder, film and toluene solution samples, we concluded that, the observed fut PL decay is caused by the polaronic exciton radiative recombination, which will diminished when the inter-chain charge transfer took place, while the slow PL decay is related to the intra-chain bipolaron recombination.
