This paper describes the synthesis and characterization of fusible and soluble polystyrene (PS) adducts of the spheroidal C{sub 60} fullerene and named flagellenes, C{sub 60}(PS){sub x`}, where x is variable (x {ge} 10). These materials spontaneously partition the fullerene moiety into domains in a nanophase-separated glass. Gel permeation chromatography and NMR confirm that mixtures of C{sub 60}(PS){sub x} adducts can be synthesized by adding living PS carbanions (number average molar mass = 2000) to C{sub 60}. Transmission electron microscopy shows nanophase-separated morphologies with fullerene-rich domains. The flagellenes could facilitate the processing and fabrication of fullerene-based materials and thereby contribute to the realization of the electronic and optical properties of C{sub 60} in technological applications.
