摘要：

We report measurements of photoluminescence efficiency and time dependence in a high-electron-affinity cyano-substituted derivative of poly(p-phenylenevinylene). We find that the luminescence is much longer lived in solid films than in solutions and interpret this result as emission in the film being from an interchain excitation. These results suggest that intermolecular interactions are an important consideration in the design of highly luminescent conjugated polymers.
