Abstract

(alpha) , (omega) -Bis(9-anthracenyl) polyenes containing 3, 4, 5, and 6 ene repeat units have been synthesized. These polyenes can be oxidized to extremely stable bipolaronic charge states in solution by SbCl5. There is significant shift in oscillator strength attending the formation of these gap states with (lambda) max for the BP states shifting into the NIR. Stable polycarbonate composites of both the neutral polyenes and the bipolarons can be cast from solution to yield optical quality films for (chi) (3) characterization.
