Purification and electronic characterisation of 18 isomers of the OPV acceptor material bis-[60]PCBM
Publikováno v:
Chemical Communications, 53(5), 975-978. ROYAL SOC CHEMISTRY
The as-produced isomer mixture of the organic photovoltaic device acceptor material bis-[60] PCBM has been purified into its constituents by peak-recycling HPLC, and those individual isomers were characterised by UV-Vis absorption spectroscopy and cy

Most experts agree that it is too early to say how quantum computers will eventually be built, and several nanoscale solid-state schemes are being implemented in a range of materials. Nanofabricated quantum dots can be made in designer configurations

Face-centered cubic phases of both the D2 and D2d isomers of the C84 anion with band fillings close to those of the A3C60 superconductors are prepared by a two-step reaction involving saturated K8+xC84 phases as intermediates. Rietveld refinement sho

Raman scattering and infrared absorption is reported for various empty and filled fullerene isomers in the low-energy range below 600 cm−1 to clarify the influence of different carbon cage structures on the bonding strength between encapsulated met

Raman scattering and infrared absorption of the C84 and Sc2@C84 isomers 23:D2d were studied at room temperature and 95 K. The results are compared to the response of pristine and doped C60. According to the lower symmetry and the higher number of ato

We report preliminary results onμ−-depolarization in C60. In contrast to graphite and diamond no clearμ−SR signal could be detected in TF-measurements in C60.

The pressure dependence of the structure of solid C70 at ambient temperature has been measured to 25 GPa by energy-dispersive X-ray diffraction. The face-centred cubic structure transforms irreversibly to a rhombohedral phase at 0.35 GPa. Crystalline
