Abstract

C60 photopolymer is a disordered mixture of short cycloadduct oligomers with various molecular geometries. We report the separation and identification of soluble C60 photo-oligomers. First we produced a series of C60 photopolymers in large quantity with a monomer recycling method. Different composition mixtures were extracted from the raw material in organic solvents. The major component of the soluble fractions is the (2 + 2) cycloadduct dimer, C120. Several higher oligomers were also detected with high-performance liquid chromatography (HPLC). Based on the decomposition products these molecules are identified as trimers and tetramers. We show the systematic variation of the relative amounts of trimers with the experimental conditions of polymerization. At lower temperatures we detected three of the possible C180-s. At high temperatures only one trimer was formed, indicating its higher stability.
