We report a new polymer combining ladder type tri(para-phenylene) (LPP) and oligo(phenylenevinylene) (OPV) segments in an orthogonal arrangement. This polymer structure was designed to decrease the quenching processes of excitons by preventing the interchain aggregation of emissive units. The synthesis, absorption, solution and film photoluminescence as well as LED device performances of this new polymer are presented. Single layer LED devices showed blue emission with an external efficiency of 0.005%. Energy transfer from LPP to OPV was observed.
