Abstract

original image

Eine andere Dimension: Zwei neuartige zweidimensionale konjugierte Polymere wurden hergestellt und mit alkoxylierten Analoga verglichen. Die Ergebnisse zeigen, dass PBDTTT-C (links) bessere photovoltaische Eigenschaften aufweist als PBDTTT-C-T (rechts) und die 2D-Strukturen somit zum Aufbau von Photovoltaikpolymeren geeignet sind.
