Summary Since buckminsterfullerene (C60) became available in large amount (1), a variety of novel materials properties of this new form of carbon, including superconductivity, ferromagnetism, optical nonlinearity, and Anti-HIV bioactivity, have been discovered (2-5). the poor tracbility of C60, however, hampers its practical applications. A tractable (soluble and fusible) form of fullerene would, in principle, open up possibilities for novel applications which otherwise are limited by its poor processability. The syntheses of fullerene polymers have attracted much attention among polymer scientists (6) because polymers containing C60 have the following advantages: (i) the fullerene polymers might be well processable (spin-coatable, solvent-castable and/or melt-extrudable); (ii) the fullerene properties can be combined with those of specific polymers; and (iii) the fullerene-containing polymers as well as surface-bound C60 layers are expected to have remarkable electronic, optical or catalytic properties. Many different kinds of fullerene functionalized polymers, including "pearl necklace", "charm bracelet" and "flagellene", have been prepared. The preparation of the functional polymers, however, sometimes requires nontrival synthetic efforts, which in turn limit the scope of applicability of the methodology. In the paper, we report a simple copolymerization reaction for the synthesis of C60-containing polyphenylacetylene (C60-PPA).
