Influences of structural properties on stability of fullerenols

Article Abstract:

Laser-induced dissociation associated with a time-of-flight measurement, synchroton radiation X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared spectroscopy (FT-IR) techniques are employed to study influences of structural properties on the stability of fullerenols. The results indicated that the stability largely depends on the quantity of the impure groups, such as highly oxygenated carbons of fullerenols, instead of the hydroxyl number.

Switchable semiconductive property of the polyhydroxylated metallofullerene

Article Abstract:

Synchrotron radiation ultraviolet photoelectron spectroscopy and TEM techniques were used for examining the temperature-sensitive property of polyhydroxylated metallofullerene film of Gd@[C.sub.82][OH.sub.x ] with special hydroxyl number. Findings reveal that the insulating properties of the polyhydroxylated metallofullerene film of Gd@[C.sub.82][OH.sub.x ] can be controllably tuned into semiconducting ones as a function of temperature.

Photochemical and photophysical properties of three carbon-bridged fullerene dimers: [C.sub.121] (I, II, III)

Article Abstract:

The study result of photophysical and photochemical properties of all three [C.sub.121] isomers (I, II, III) and their stability at different conditions reveal them be a good electron acceptors, forming a 1:2 complex with DMA in toluene which could be used as a basic unit in polymer photovoltaic cells.
