A new poly(ladder-type pentaphenylene) bearing aryl groups at all bridgehead positions has been prepared. In comparison to previously reported bridged poly(p-phenylene)-type polymers such as polyfluorene and polyindenofluorene, this polymer is optimized for maximum overlap of the blue emission with...
