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 the sensitivity of the human eye. Furthermore, the introduction of aryl substituents at all the bridgeheads
