SYNTHESIS, CHARACTERIZATION AND OPTICAL LIMITING PROPERTIES OF POLYCARBONATES CONTAINING FULLERENE DERIVATIVE

摘要

Fullerenated polycarbonates (TCNEOC_(60)-PCs) with an interesting optical limiting behavior are obtained by direct reaction of TCNEO-C_(60) with PC using A1C1_3 as catalyst. The electron-accepting ability of TCNEO-C_(60) is stronger than C_(60), and TCNEOC_(60)-PCs limit strong 532nm optical pulses more effectively than C_(60_-PC. This suggests that increasing the electron-accepting ability of fullerene will be effective in improving the optical limiting properties of fullerenated PC.
