Abstract

original image

Starre π-konjugierte Brücken wie die Ethinylgruppe sind geeignet, um das π-System eines Phthalocyanins effektiv an das Leitungsband von TiO2 zu koppeln. Eine Reihe von Zinkphthalocyanin-Photosensibilisatoren mit Carboxyethinyl-Ankergruppen wurde synthetisiert. Solarzellen, die mit der gezeigten Verbindung sensibilisiert wurden, zeigten Wirkungsgrade von 5.5 % und 6.1 % unter 100 (1 sun) bzw. 9.5 mW cm−2.
