Two new [60]fullerene pyrrolidine derivatives 2 and 3 were synthesized and characterized by 1H NMR, 13C NMR and MS. Their photophysical processes have been investigated by using laser flash photolysis. The experiments show quenching of oligomer singlet excited state and the evidence of the fullerene singlet excited emission. And the intramolecular of electron transfer and also energy transfer of 2 and 3 occurred and the triplet excited state of fullerene moiety in 2 and 3 have different lifetime due to their different structures. A photovoltaic device using compound 2 as the only photoactive material has also been investigated which showed the energy conversion efficiency is 0.011%. 相似文献

Abstract A series of [60]fullerene pearl-necklace polyamides, consisting of equatorial-[60]fullerenobisacetic acid and various chromophoric aromatic diamines, were synthesized by a phosphorylation route using large amounts of triphenyl phosphite and pyridine as condensing reagents with stepwise addition of the condensing reagents. In the present polymers, [60]fullerene pearls and diamine linkers were attached to one another by cyclopropane connectors. The polyamides had weight-average molecular weights (Mw)of 4.5-5.0×104 g/mol and inherent viscosities (n inh) of 0.3-0.4 dL/g in N, N-dimethylacetamide (DMAc) at 30 °C. They had glass transition temperatures at 30-125 °C and decomposition temperatures at 300-310 °C. The UV-VIS spectra in DMAc exhibited broad absorption with λmax at 310-390 nm tailing to longer wavelengths. 相似文献

Abstract The formation of all-carbon [60]fullerene derivatives was observed in the course of the thermolysis of methano-fullerene derivatives. IR, UV-Vis, GPC, 13C-NMR, TG-MS, TOF-MS and STM data are consistent with the formation of all-carbon [60]fullerene oligomers without a direct connection between fullerene cages but through one or two carbon atoms as bridges. Molecular masses up to 8000 amu have been detected by mass spectroscopy. 相似文献

We report the synthesis and characterisation of a series of ferrocenylfullerene compounds, and some new ferrocene derivatives required as intermediates. The new fullerene species are Fc-[60]fullerene, (8); Fc-C=C-[60]fullerene, (10); Fc-C=C-C=C-[60]fullerene, (12); and (η-C5H4SiBu3)Fe(η-C5H4)-[60]fullerene, (14). 相似文献

Abstract The antibacterial activity of [60]fullerene (C60), dissolved with poly(vinylpyrrolidone) K30 (PVP), was studied. Under photo‐irradiation, C60/PVP aqueous solutions showed antibacterial activity, whereas PVP solution alone or fullerene solutions in the absence of light showed no activity. These results reveal that C60 is a potentially good device as a photoinduced antibacterial agent. 相似文献

Novel supramolecular nanocapsules consisting of [60]fullerene and the macrocycle cucurbit[7]uril via self-assembly are reported. The nanocapsules, which were synthesized in a two-phase reaction at room temperature, were obtained in good yields. The stoichiometry of the product was found to be 1:2. 相似文献

The addition reactions of [60]fullerene to benzyl amine and anthracene were studied by using spectrophotometry. The kinetic measurements show minima if the absorbance at a wavelength of 595 nm is plotted versus time. The minima obtained from the spectrophotometric kinetic measurements can be attributed to the formation of intermediates of C60 due to the single-electron transfer mechanism for the amine addition and electron deloalization processes for the concerted [2 + 4]cyclo-addition. 相似文献

Diels-Alder reaction of 4-amino-o-quinodimethane (6) with [60]fullerene (1) affords the thermally stable and chemically reactive adduct 7(n). The nucleophilic amino group of 7(n) is well suited for the covalent attachment of different molecules to the [60]fullerene core by further chemical reactions. 相似文献

A new, scalable, one-pot solution phase synthesis of the D2 h symmetric trans-1 bisanthracene adduct of [60]fullerene is described. The highly regioselective reaction utilizes commercially available 9,10-dihydroanthracene, 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and [60]fullerene and exhibits an unusual temperature dependence. 相似文献
