Progress in micro- and nanoelectronics is impossible without new materials investigation. In recent years there were a lot of publications dedicated to fullerenes [1], from one hand, and conducting polymers from another [2]. We investigated fullerene-containing polymers [3,4] to clear up their physical properties and electronic structure.

The aim of this work was to create fullerene films on polymeric substrates with non wan-der-waals interaction in heterostructures interface and to investigate their properties.

The films were prepared by sublimation in vacuum and were deposited on polymers substrates of polyacrylonitrile (PAN) and cycled PAN. The heterostructures had strong adhesion and crystal phase of C60 ascertained by X-ray diffraction. Photoluminescence (PL) investigations of the heterostructures showed additional peaks corresponding to the twisted electronic structure of C60 under influence of polymer pi-electronic system.

In this work we discuss the origin of X-ray halo in polymeric substrates and PL features of the heterostructures.
