“…On the other hand, the reverse side of this cast film decreased remarkably its fluorescent intensity compared to that of the surface. A similar result was observed in the cast PMMA film treated with R F -(ACA) n -R F /SiO 2 /C 60 nanocomposites, and a strong fluorescent intensity was obtained on the surface side (see No 2 in ). However, in the case of the modified PMMA film treated with R F -(ACA) n -R F /C 60 nanocomposites (see No 3 in ), a fluorescent intensity was also found to increase on the reversed side, compared to that of No 1 or No 2.…”

Fluoroalkyl end-capped acrylic acid oligomers/fullerenes nanocomposites reacted smoothly with tetraethoxysilane (TEOS) and silica nanoparticles under alkaline conditions to give fluoroalkyl end-capped oligomers/silica composites-encapsulated fullerenes. Interestingly, these isolated fluorinated composites were found to afford nanometer size-controlled colloidal particles with a good dispersibility in a variety of organic solvents including water. More interestingly, these fluorinated silica nanocomposites-encapsulated fullerenes were applied to a new type of surface modification agent, and these nanocomposites were able to disperse well above the poly(methyl methacrylate) films to exhibit not only surface active property imparted by fluorine but also a unique characteristic related to fullerenes in the nanocomposites on the surface, effectively.

“…Composites of fullerenes with various polymers are very important from the developmental viewpoints of new functional materials 2,3) . In the studies on the composites of fullerenes, it is in particular interest to develop the novel surface modification of common polymeric materials by fullerenes from a practical point of view.…”

“…There are two items to note: the first is that the cell responds differently to the positive and the negative parts of the cycle. This has already been reported in the literature: the mobility of electrons and holes in PVK:C 60 is different [18][19][20], and C 60 has different hole/electron acceptor levels [21]. The second observation is that the largest beam coupling is at intermediate voltages.…”

Light-activated modulation and coupling in integrated polymer–liquid crystal systems

We explore the transfer of an incident light pattern onto the liquid crystal (LC) bulk in a photorefractive cell through an integrated photoconducting layer that modulates the electric field applied to the device. The electrical properties and the strength of modulation are investigated as a function of the incident light intensity as well as the frequency and amplitude of the applied voltage, for two LCs with very different electrical conductivity. A simplified electrical model of the cell is proposed, demonstrating that the LC conductivity is a key factor determining the beam-coupling strength.

“…Polyvinylcarbazole (PVK) doped with a mixture of C 60 and C 70 has been reported to exhibit exceptionally good photoconductive properties 258 which may lead to the development of future polymeric photoconductive materials. The effects of the fullerenes (-2.7% by weight) on the charge generation and transport still need to be understood.…”

A review of the structure and properties of fullerenes is presented. Emphasis is given to their behavior as molecular solids. The structure and property modifications produced by alkali-metal doping are summarized, including modification to the electronic structure, lattice modes, transport, and optical properties. Particular emphasis is given to the alkali-metal-doped fullerenes because of their importance as superconductors. A review of the structure and properties of fullerene-based graphene tubules is also given, including a model for their one-dimensional electronic band structure. Potential applications for fullerene-based materials are suggested.
