FULLERENE POLYMERS WITH TUNABLE OPTICAL PROPERTIES

Light transmission spectra of THF solutions of poly (C_(60)-co-methyl methacrylate)s andpoly (C_(60)-co-styrene)s continuously red-shift with increasing concentration. Formation offullerene nanoclusters may be responsible for the unusual spectral shift with concentration.It has long been scientists' dream to "tune" material's properties by simple means, and theC_(60)-containing polymers represent such a group of novel materials whose optical propertiesare predictably and reversibly tunable by a simple change in concentration.
