Intramolecular alkyne aromatization is a powerful tool that enables the synthesis of nonplanar polycyclic aromatic hydrocarbons. Herein, an unexpected intramolecular via trifluoroacetic acid-promoted cyclization described, in which two structural isomers, expanded [9]helicene (1) and π-extended double [4]helicene (2) are obtained. A possible rearrangement mechanism proposed to account for forma...

Multifunctional electrodes for structural supercapacitors are prepared by vacuum infiltration of single-walled carbon nanotubes (SWCNTs) into woven fibers (CFs); the use reductive charging chemistry to form nanotubide solutions ensured a high degree individualization. The route is highly versatile, as shown comparing four different commercial nanotube feedstocks. In film form, pure networks (“b...

In the quest to increase battery performance, nanostructuring electrodes gives access architectures with electrical conductivity and solid-state diffusion regimes not accessible traditional based on aggregated spherical microparticles, while often also contributing cyclability of otherwise unstable active materials. This work describes where material current collector are formed as a single nan...

Macroscopic arrays of highly-crystalline nanocarbons offer the possibility modifying electronic structure their low dimensional constituents, for example through doping, and studying resulting collective bulk behaviour. Insertion electron donors or acceptors between graphitic layers is an attractive method to reversibly increase charge carrier concentration without disruption sp2-conjugated sys...

Uniform carbon nano test tubes including magnetic metal particles inside their one-dimensional cavities were synthesized by the template method. The "as synthesized" metal-filled test tubes (35 nm in diameter and 1400 nm in length) were dispersible in ethanol, but not in water. To improve the water-dispersibility of the test tubes, their surface was treated with hydrogen peroxide and, as a resu...

Layer-like nanocarbons with high surface area and good conductivity are promising materials for supercapacitors due to their good ability for effective charge-transfer and mass-transfer. In this paper, stacked layer-like porous carbon containing RGO (reduced graphene oxides) (LPCG) was constructed via the GO-induced assembly of gelatin followed by carbonization and activation processes. Under s...
