C-60 complexation revisited

Nature, 1994
In the recent paper by Atwood et al. (Nature 368, 229-231, 1994) on a purification procedure for C60 and C70 by selective complexation with calixarenes, it was implied that we had previously studied the complexation of C60 with cyclodextrins (Williams, R. M. & Verhoeven, J. W., Recl. Trav. Chim. Pays-Bas 111, 531-532, 1992). In fact we used calix[8]

The reactivity of C+60 and C2+60

International Journal of Mass Spectrometry and Ion Processes, 1991
Abstract The metastable eliminations of C 2 from C + 60 and C 2+ 60 , generated by electron ionization from Buckminsterfullerene, C 60 , were studied by high resolution reverse geometry mass spectrometry. The kinetic energy release distributions for C + 60 and C 2+ 60 , are nearly the same and in excellent agreement with previous results ...

Nanoscale C 60 aggregates in solution

SPIE Proceedings, 1997
Formation of C60 aggregates has been found in toluene, benzene, and carbon disulfide (CS2) solutions by means of photoluminescence spectroscopy. From the detailed investigation of the temperature dependence of luminescence, it has been confirmed that the C60 aggregates are formed at freezing temperature of these solvents in the cooling process and are ...

Preparation of C 60 bonded Poly(N-vinylcarbazole) with C 60 Cln/CuCl/Bpy catalyst system

Polymer Bulletin, 2002
C60 bonded poly(N-vinylcarbazole) has been synthesized by C60Cln (the average value of n is 20)/CuCl/2,2'-bipyridine (Bpy) catalyst system and its structure was analyzed by UV-Vis and proton NMR. The polymerization mechanism was proposed proceeding via an atom transfer radical polymerization (ATRP).

Collective Electronic Oscillations on C 60

1995
The C 60 molecule, known also as buckyball, has a very interesting history. During 1980–85 mass spectroscopic studies of carbon by laser vaporisation of graphite revealed magic numbers of carbon clusters [1,2]. A special stablity was found for C 60 and C 70 in the joint Sussex-Rice experiment [2] and at the same time the correct structure was ...

Collisions of O$^{q+}$ with Neutral C$_{60}$ Charge Transfer and Fragmentation

Journal of Physics B: Atomic, Molecular and Optical Physics, 1998
Fragmentation of C-60 fullerenes by collisions with multiply charged Oq+ ions (1 less than or equal to q less than or equal to 7) has been studied experimentally for Oq+ collision energies of 1.16 keV amu(-1) For high projectile charges the potential energy of the projectiles is mainly responsible for the processes induced: the fragment spectra are ...

Laena=Lesbia a Catul, c.60?

1987
La poesia número 60 de Catul, la darrera de les peces polimètriques del seu liber, ha provocat de sempre moltes preguntes i inquietuds des de diferents punts d'interès: la ubicació mateixa de la poesia (és un poema tancat o es tracta d'un fragment desconnectat?); la seva relació amb els carmina immediatament anteriors a ell (per què Catul trenca una ...
