“…The effects of the vacuum sublimation process on the composition of C 60 /C 70 films are reported by Li et al (115). A TG run carried out for C 60 /C 70 mixture separated from soot by benzene Soxhlet extraction demonstrates a sublimation process.…”

“…The signal Ia constitutes around 20% of the overall intensity within the C1s spectrum, while the signal IIa corresponds to 80%. The non-oxidized C forms (peak IIa) originate most likely from fullerene cages and CuPc benzene rings since both species possess high thermal resistances [24,25]. The presence of this signal was not clearly determined for the non-annealed sample B due to the significant superiority of the APTMS organic residuals.…”

We have studied the heat treatment influence (room temperature to 400°C) on thin aminopropyltrimethoxysilane (APTMS)-based films incorporated with [6,6]-phenyl-C61-butyric acid methyl ester (PCBM), copper phthalocyanine (CuPc), and three-dimensional structure cage polyhedral oligomeric silsesquioxanes (POSS) by X-ray photoelectron spectroscopy and capacitance voltage technique. We discuss the interplay between the temperature degradation of the organic components (aminopropyl groups, sp 3 -based carbon bonds of APTMS, cyclopentyl rings, and vinyl functional group of POSS) and the thermal stability of the fullerene molecules (PCBM), benzene rings (CuPc), and the POSS inorganic cages. We observe the formation of Si-O-Si bridges between the POSS inorganic cages and the SiO 2 -enriched matrix which contains also fullerene molecules and benzene rings.
