Optical absorption spectra of higher fullerenes (C70 and C76) as well as of C60 are calculated by a tight binding model with a long range Coulomb interaction. A reasonable parameter set gives calculated spectra which are in overall agreement with the experiments of of C60 and C70 in solutions. The variations of the spectral shape are discussed relating with the symmetry reduction going from C60...

We propose a two-state electric field-driven room-temperature single-molecule switch based on a dipolar molecule enclosed inside ellipsoidal fullerene C70. We show that the two low-energy minima of the molecular dipole inside the C70 cage provide distinguishable molecular states of the system that can be switched by application of an external electric field.

The regioselective synthesis of easily isolable pure bismethano derivatives of C60 and C70 with high steric congestion is described using 1,3-dibenzoylpropane bis-p-toluenesulfonyl hydrazone as the addend precursor. When the addition occurs at two [6,6] ring junctions within the same hexagon, bisadducts with mirror symmetry are obtained for both C60 and C70. When the addition occurs at two [5,6...

To obtain direct evidence for the fullerene-exchange reactions from the γ-cyclodextrin cavities to the lipid membranes following the addition of a C70·γ-cyclodextrin complex, we monitored the dynamic behaviours of the giant unilamellar vesicles. A number of C70 aggregates generated in the lipid membranes moved about vigorously.

Efficient photocatalytic disinfection of Escherichia coli O157:H7 was achieved by using a C70 modified TiO2 (C70-TiO2) hybrid as a photocatalyst under visible light (λ > 420 nm) irradiation. Disinfection experiments showed that 73% of E. coli O157:H7 died within 2 h with a disinfection rate constant of k = 0.01 min(-1), which is three times that measured for TiO2. The mechanism of cell death wa...

Excitation–emission matrix (EEM) fluorescence spectroscopy of unmodified (pristine) fullerenes C60 and C70 in benzene, toluene, n-hexane at room temperature was used for their quantification by solvent-dependent EEM bands specific to each fullerene. The intensity parameters depend on both the fullerene solvent provide conditions mixtures without separation. detection limits benzene under select...

C70-based acceptors show great potential in polymer solar cells (PSCs). Two high-LUMO C70 acceptors, the 66π OQMF70 and the 64π bis-OQMF70, based on methano[70]fullerene (C70CH2) were developed. An outstanding power conversion efficiency (PCE) of 6.88% was obtained from OQMF70:P3HT solar cells.

The C terminus of Hsp70 interacting protein (CHIP) E3 ligase functions as a key regulator of protein quality control by binding the C-terminal (M/I)EEVD peptide motif of Hsp/c70(90) with its N-terminal tetratricopeptide repeat (TPR) domain and facilitating polyubiquitination of misfolded client proteins via its C-terminal catalytic U-box. Using CFTR as a model client, we recently showed that th...

The antioxidant potential (capacity and activity) of aqueous fullerene dispersions (AFD) non-functionalized C60, C70, Gd@C82 endofullerene (in micromolar concentration range) was estimated based on chemiluminescence measurements the model luminol generation organic radicals by 2,2?-azobis(2-amidinopropane) dihydrochloride (ABAP). capacity TRAP method, from half-suppression, suppression area in ...
