Abstract

original image

Photocurrent-generating fullerenes: New fullerene derivatives bearing a phosphonic acid linker (e.g., C60(C6H4-Ph-4)5(CH2)6PO(OH)2) form self-assembled monolayers (SAMs) on indium tin oxide (ITO) and SnO2 surfaces, and generate both anodic and cathodic photocurrent in the presence of sacrificing reagents.
