Stable multilayer systems of C60-based materials were assembled on photactive indium tin oxide (ITO) electrodes by supramolecular layer-by-layer organization. The assembled ensembles comprise a positively charged fulleropyrrolidinium salt (see scheme) and a series of positively charged ruthenium(II)-polypyridyl-fullerene donor–acceptor dyads. Upon irradiation with light of an appropriate wavelength efficient generation of photocurrent can be observed, whose intensity increases linearly with the number of deposited monolayers.

Abstract
Stable multilayer systems of C60-based materials were assembled on photactive indium tin oxide (ITO) electrodes by supramolecular layer-by-layer organization. The assembled ensembles comprise a positively charged fulleropyrrolidinium salt (see scheme) and a series of positively charged ruthenium(II)-polypyridyl-fullerene donor–acceptor dyads. Upon irradiation with light of an appropriate wavelength efficient generation of photocurrent can be observed, whose intensity increases linearly with the number of deposited monolayers.File in questo prodotto:
