Abstract

A new series of copolymers (PSiFF) based on 3, 6-silafluorene and 2, 7-fluorene were synthesized via the Suzuki polycondensation. The influences of the 3, 6-silafluorene content in the copolymers on the thermal, photophysical, electroluminescence and electrochemical properties were investigated. The incorporation of 3, 6-silafluorene into the polyfluorene main chain not only suppressed the long-wavelength emission but significantly improved ...
