Diels -Alder reactions of [60]fullerene with 1,2,4,5-tetrazines and additions to [60]fullerene-tetrazine monoadducts
<p>The Diels-Alder reaction between [60]fullerene and 1,2,4,5-tetrazines was studied. Under conditions of total darkness, [60]fullerene reacts with tetrazines to form bicyclic intermediates which immediately extrudes nitrogen to yield C2nu symmetric monoadducts. Thus, 3,6-diphenyl and 3,6-di-(2 …

Towards a fullerene-based nanotechnology: The (10,10) tube
While fullerenes form in yields exceeding 30% by mass when a laser generated pure carbon vapor is allowed to condense under annealing conditions, more than 70% of all vaporized carbon assembles in the form of single-wall fullerene nanotubes (SWNTs) in the presence of certain transition metal SWNT …

Fullerene hydrides and studies toward the syntheses of fulvalenes
… was used to synthesize highly hydrogenated fullerenes, C60H36, C60H38, C 60H40, C60H42 and C60H 44. 1H- and 13C-NMR spectra of HPLC purified fractions show that more highly hydrogenated fullerenes exhibit signals that are shifted upfield. The opposite trend was observed in 3He NMR spectra of …

Generation of Heptagon-Containing Fullerene Structures by Computational Methods
Since the discovery three decades ago, fullerenes as well as metallofullerenes have been extensively investigated. However, almost all known fullerenes follow the classical definition, that is, classic fullerenes are comprised of only pentagons and hexagons. Nowadays, more and more evidence, from …

Fullerene C60 based nanostructures by self-assembly and molecular recognition
… structures have been studied quite extensively, fullerene C60 nanostructures have not received much attention. Furthermore, carbon nanostructures experience a self-healing process when subjected to intense conditions, this created a scope to explore and investigate the effects of such conditions …

Synthesis, characterization, and thermal properties of ceramic-fullerene thin films
Thin films containing ZrO2 and dispersed fullerenes have been synthesized using codeposition processing, and the role that dispersed fullerenes play in the thermal behavior of co-deposited films has been characterized. The presence of C60 within the films has been confirmed using a new application …

Stability of zinc phthalocyanine and fullerene C60 organic solar cells
Organic solar cells promise electricity generation at very low cost, and higher installation flexibility as compared to inorganic solar cells. The lower cost is achieved by cheaper semiconductors and easier manufacturing processes. The flexibility is naturally given by these ultra-thin, amorphous …

Electrical and optical characterisation of bulk heterojunction polymer-fullerene solar cells
Manufacturing polymer-fullerene solar cells can be less expensive and less complicated as compared to inorganic solar cells. We studied transport properties of the polymer- poly3(hexyl-thiophene) (P3HT), fullerene - [6,6]-phenyl-C61 butyric acid methyl ester (PCBM), and P3HT:PCBM blends of selected …
