Abstract

original image

Setz einen Ring drauf: Die Synthese sterisch gehinderter Polyarylene gelingt durch Benzanellierungsreaktionen an jeder C[TRIPLE BOND]C-Bindung von Polyphenylenethinylen (siehe Bild), einem der am einfachsten zu synthetisierenden und vielseitigsten konjugierten Polymere. Eine Isotopenmarkierungsstudie und mehrere komplementäre spektroskopische Methoden ergaben, dass die Benzanellierungen hochspezifisch und effizient sind.
