摘要：

(Graph Presented) Energy transfer at the interface of two dissimilar conjugated polymer chains (see picture; DMOS = 2-dimethyloctylsilyl-p- phenylenevinylene; MEH = 2-methoxy-5-(2′-ethylhexyloxy)-p- phenylenevinylene) has been studied using single-molecule spectroscopy. Morphological features control energy-transfer processes between the blocks and lead to strongly heterogeneous efficiencies of energy transfer. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
