Abstract

original image

Ein homogenes Dreikomponenten-Katalysatorsystem mit einem IrIII-Komplex als Photosensibilisator, künstlichen Hydrogenasen mit einem Dieisenkern und dendritischen Gerüsten als Protonenreduktionskatalysator und Triethylamin als Elektronendonor wurde synthetisiert. Die anfängliche Umsatzfrequenz bei der photokatalytischen Wasserstoffentwicklung betrug 7240 h−1 und die Quantenausbeute bis zu 28 %.
