Fullerene derivatives especially [1,1]-phenyl-C61-butyric-acid-methyl-ester (PC61BM) have been commonly used as electron transport layers and additives of inverted (p-i-n) perovskite solar cells (PVKSCs); however the dielectric constant (the εr) PC61BM (3.8) is much smaller than those organolead halide hybrid perovskites (6.5 for CH3NH3PbI3 [MAPbI3]), resulting in unfavorable exciton dissociati...

We report on the synthesis of C60 and C70 monoadducts at room temperature through Bingel reaction; employing acetylacetone as ligand; in presence DBU (1,8-Diazabicyclo [5.4.0] undec-7-ene), carbon tetrabromide (CBr4), o-dichlorobenzene. Diacetylmethane-[C60-Ih]-fullerene-[5,6] diacetylmethane-[C70-D5h]-fullerene-[5,6] were obtained with yields 69% 44%, respectively. The products purified by col...

We have investigated the adsorption of some amino acids and an oligopeptide by fullerene (C60) and fullerene nanowhiskers (FNWs). C60 and FNWs hardly adsorbed amino acids. Most of the amino acids used have a hydrophobic side chain. Ala and Val, with an alkyl chain, were not adsorbed by the C60 or FNWs. Trp, Phe and Pro, with a cyclic structure, were not adsorbed by them either. The aromatic gro...

The modifying effects of the products of the equimolar addition Of DL-alanine and DL-alanyl-DL-alanine to fullerene C60 on the structure and permeability of the lipid bilayer of phosphatidylcholine liposomes has been studied using the luminescence probe technique. It is shown that these water soluble amino acid and dipeptide derivatives of fullerene (C60-AD) are quenchers of pyrene fluorescence...

We have found that compounds formed between fullerenes and RuO4 can be hydrolyzed to the corresponding diols. RuO4 is easily prepared by the reaction of NaIO4 with RuO2 hydrate and subsequent extraction into CCl4. Due to a very low solubility of C60 or C70 in CCl4 we chose 1,2,4trichlorobenzene (TCB) as a main component of the reaction medium. TCB is an excellent solvent for C60 or C70 and is a...

In the present work, we report the first experimental evidence of entropically driven C60 fullerene aggregation in aqueous solution, occurring with nearly zero enthalpy change.

Partition and localization of C60 and its derivative C60(OH)18-22 in lipid membranes and their impact on mitochondrial activity were studied, attempting to correlate those events with fullerene characteristics (size, surface chemistry, and surface charge). Fluorescence quenching studies suggested that C60(OH)18-22 preferentially populated the outer regions of the bilayer, whereas C60 preferred ...

New molecular complexes of fullerenes C60 and C70 with tetraphenylporphyrins [M(tpp)] in which M-H2, MnII, CoII, CuII, ZnII and Fe(III)Cl, have been synthesised. Crystal structures of two C60 complexes with H2TPP, which differ only in the number of benzene solvated molecules, and C60 and C70 complexes with [Cu(tpp)] have been studied. The fullerene molecules form a honeycomb motif in H2TPP.2C60...

Fullerene C60 powder was loaded by 1 N normal force and exposed to sliding under different frequencies for 15 min. It is shown that the velocity of movement determines stability fullerene powder. At slow with a frequency Hz force, structure remains undamaged after min sliding. On contrary, high velocities 10 50 affected fragmentation C60, which resulted in reduction coefficient friction (COF). ...

Codeposition of C60 and the three-dimensional molecular hydrocarbon 1,3,5,7-tetraphenyladamantane (TPA) on Au(111) leads to the spontaneous formation of molecular nanostructures in which each fullerene is locked into a specific orientation by three surrounding TPA. Scanning tunneling spectroscopy shows that the electronic coupling of C60 with the surface is significantly reduced in these nanost...
