These polymers are air and water stable and thermally stable and appear to form discrete spherical clusters of approximately 800-1000 Angstrom diameter, and linear assemblies several micrometers long. The polymers can be suspended in many organic solvents, swell dramatically in water, and are miscible with a variety of other polymers, such as polystyrene, casting processable films. The polymer films are both photoluminescent and electroluminescent. Electronic absorption, fluorescence, and H-1 NMR spectra along polymeric materials are reported. 关键词: FULLERENES; C-60; TUBULES; COLLECTIVE EXCITATIONS; COLLOIDAL METAL; CLUSTERS; PARTICLES; CHEMISTRY; STATE; SIZE; CDS; MOLECULES CHEMISTRY; STATE; SIZE; CDS; MOLECULES
