Structural phase transitions of C60 under high-pressure and high-temperature

Structural phase transitions of C-60 under high-pressure and high-temperature are presented in a concise overview extracted from updated literature. Primarily focused on polymerization of C-60: ordered-1D, 2D, 3D polymers- and disordered-graphite-like and diamond-like-phases as well as spatially constrained 1D fullerenes-encapsulated fullerenes, i.e. peapods. Special accent is given to X-ray diffraction data addressing complexity and limitations on data analysis and interpretation for low atomic number, multiphase, textured and disordered samples. Cutting-edge experimental work, description of novel X-ray based experimental methods as well as outline for future directions in this research field are presented. (C) 2014 Elsevier Ltd.
