Polymerization of C60 fullerene thin films by UV pulsed laser irradiation

Novel fullerene-functionalised poly(terthiophenes)

“…In contrast, the Raman spectrum of P(TTh-BB) displayed a significant difference under 500 cm À1 in Zone E' assigned to the pendent C 60 moiety in P(TTh-BB) and not observed for P(TTh). This is consistent with the weak intermolecular forces and icosahedral symmetry associated with isolated C 60 molecules [28].…”

Fullerene-multiwalled carbon nanotube complexes for bulk heterojunction photovoltaic cells

“…Fullerene molecules are known to polymerize under high temperature, pressure, and under UV irradiation. 12,13 It is possible that such interactions took place here. The formation of gel-like structures around the MWNT is quite evident from the SEM images.…”

“…Similar phenomenon has been reported on photopolymerized C 60 films, indicating lower icosahedral symmetry of fullerene molecules. 13 The broad IR absorption band centered around 1404 cm −1 can be seen on the C 60 and c-MWNT/ C 60 spectra but it disappears on the o-MWNT/ C 60 spectrum and a weak absorption peak appears at 1386 cm −1 , instead. This peak corresponds to amine of the o-MWNT.…”

Preparation of Fullerene (C60) Based SiO2 Sonogel Hybrid Composites: UV Laser Induced Photo-Polymerization, Morphological, and Optical Properties

“…36 experiments have been shown to be very efficient for determining different phase transformations of UV-laser irradiated pristine C 60 thin films. [38][39] In general, this technique takes advantage of the mechanical waves generated on the surface of the material by the laser-matter interactions; such waves traveling at the speed of sound across the material depth are detected via a piezoelectric transducer located on the other side of the sample. The acoustic signal is a consequence of a pressure wave traveling in the material, induced by the incidence of the laser beam.…”
