Description

<jats:p><jats:bold>Hollow capsules with polarity gradients</jats:bold> can be built up by a layer‐by‐layer technique. After laser excitation, long‐lived charge separation was observed. Time‐dependent measurements, observing the decay of pyrene cation and anion absorption, show that the sample configuration has an influence that can be ascribed to the polarity gradient The charge separation can therefore be predicted due to the establishment of the polarity gradient over nanometer dimensions.</jats:p>
