This review is devoted to the works of the last decade on the properties of donor-acceptor complexes of fullerene performed by Raman scattering and X-ray diffraction analysis at high pressure using diamond anvils. The issues of charge transfer from a molecular donor to fullerene acceptor at high pressure, kinetics of photopolymerization at ambient and high pressure, energy barrier of photopolymerization, the types of photooligomers formed and their thermal stability are considered.
