[60]Fullerene solid films deposited by vacuum sublimation on polymer substrates were studied by methods of X-ray diffraction structure analysis, IR optical transmission, and laser-excited photoluminescence (PL) spectroscopy. Mechanism of good chemical adsorption to centers with unsaturated bonds C=N and CN was on trial. Room-temperature PL band at 1.78 eV has its origin in interface chemical bonds or molecular complexes, that arise most probably according to Diels–Alder cyclo-addition of fullerene and polymer molecules.
