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.
