We investigated an interaction of C₆₀ fullerene with different polymers. First of all we were interested in influence of polymeric molecules on fullerene energetic state in polymer media and transformation of fullerene optical transmissions system under influence with polymer.

Two types of fullerenecontaining polymers were investigated: polystyrene-C₆₀ (PS-C60) and polydimethylphenylene oxide-C₆₀ (PPhO-C60). Polystyrene chains have strong covalent bond with fullerene backbone and provide star-burst macromolecule. We discovered blue shift in photoluminescence (PL) spectra of the star-burst PS-C60 (beside pure C₆₀) depending on a number of attaching chains. That meant a fact of C₆₀ HOMO-LUMO gap increasing after new bounds formation. The increasing did not depend on a type of bond with fullerene: C-C or C-H and main cause of the shift was the fact of double bonds breakage on C₆₀, whereas a type of addenda or bonds had an energetic effect of second order of magnitude.

A samples of PPhO-C60 were observed by PL and IR-absorption methods and showed molecular complexes formation with a character PL peak at 1.77 eV. Its energetic location did not depend on concentration of C60 and PPhO. The same peak was observed in PS-C60 complexes that was an evidence of universal interaction mechanism between fullerene pi-electronic system and pi-system of polymer resulting the molecular complexes fullerene-polymer formation.

The fundamental investigations of fullerene-containing polymers were applied by us for creating C₆₀ films on polymer substrates.
