Amphiphilic cyclodextrin–fullerene conjugates have potential biological activity, due to their water solubility. In order to study the influence of the linker of these conjugates on solubility and aggregation, a permethylated β-cyclodextrin–C60 conjugate with a short linker –(CH2)2NHCO–, which is attached to the secondary face of β-cyclodextrin was synthesized. Its solubility in water and its U...

Rigid and soluble electron donor-acceptor conjugates combining exTTF and/or TTF as donors and C60 as acceptor have been synthesized; fluorescence and transient absorption measurements confirm the generation of charge-separated radical-ion pairs with lifetimes in the micros timescale.

This work describes the application of oxo-derivatives of fullerene C60 and pristine fullerene as a nanocomposite in polymerous nanofibres. In this work we used oxofullerene derivative, of which preparation was presented by the authors of the State office for nuclear safety (Prague) on Nanocon 2009 and on Nanocon 2010 [1, 2]; there was presented its application in vivo as a radioprotective agen...

Small-angle neutron scattering experiments by interpenetrating networks of poly(carbonate-urethane) and polyvinyl pyridine reveal that there is some degree of microphase separation at all compositions, possibly, in some compositions, into a bicontinuous phase. The domain size is some undred angstroms in the samples with only one glass transition

Self-assembly allows new opportunities to control the morphology and properties of fullerenebased materials. By using the electron-accepting underivatized C60 and electron-donating pyridine groups of a polystyrene-block-poly(4-vinylpyridine), PS-block-P4VP, we here show the first example that charge-transfer complexation between fullerenes and block copolymers can essentially modify the self-as...

A pyridine-functionalized pyrazolinofullerene (1) was synthesized in 42% yield via an improved one-pot reaction of C60, 3,6-di(2-pyridyl)-1,2,4,5-tetrazine, and water. The structure of 1 was unambiguously determined by X-ray diffraction of its single crystal. Due to the coordination capability of the functional groups on fullerene, compound 1 was used as a buffer layer to modify ZnO in inverted...

Three C60-DPAF conjugates were synthesized with one as a linear monoadduct and two as branched or starburst multiadducts in structure for the investigation of chromophore antenna number-dependent tunability of RF-responses at 0.5−18 GHz. The effect was photoinduced by the generation of surface plasmonic resonance (SPR) at the surface of trilayered core−shell nanoparticles (NPs) consisting of a ...

Water-soluble C60-porphyrin hybrid molecules were first synthesized toward their pharmaceutical applications.

Various chemicals including p-phenylenediamine, n-propyl gallate, 1,4-diazobicyclo[2,2,2]-octane and Citifluor were tested to determine their effectiveness in retarding the fading of fluorescein-conjugated antibody bound to eosinophil granule major basic protein in tissues. Immunofluorescence fading and intensity were measured quantitatively using the Zeiss Zonax microphotometer system. All of ...

We describe the design and synthesis of a novel functionality-rich, homochiral macrocycle, possessing the overall molecular D2 symmetry, in which multivalency is introduced into the covalent framework by means of four suitably positioned pyridine moieties. The macrocycle synthesis is carried out with functionalized, enantiopure 1,1'-binaphthyl synthons as the source of chirality by means of a r...
