title: Construction of long-wavelength-light photocurrent generation system based on self-assembled monolayer of cobaltadithiolene [60]fullerene complex.
abstract: [60]Fullerene pentaester and pentaacid derivatives bearing cobaltadithiolene dyes were successfully synthesized under mild reaction conditions. Self-assembled monolayers (SAMs) of the pentaacid derivative were prepared by an immersion method and the photocurrent generation properties of the SAMs were measured. Due to the introduction of the light-absorbing cobaltadithiolene moiety, the range of available wavelengths for photoelectric conversion was extended to lambda = 700 nm, which is longer than that of conventional penta(organo)[60]fullerene carboxylic acids.
