We propose the novel σ-π conjugated polymer, poly(biphenyl germanium) grafted with two electron-donating acridan moieties on the germanium (Ge) atom for use as the host material in polymer light-emitting diode (PLED) with sky-blue emitting thermally activated delayed fluorescence (TADF) material, DMAC-TRZ as the guest. It gives the high triplet energy (ET) 2.86 eV, which is significantly higher than those of conventional π-π conjugated polymers (ET= 2.65 eV as the limit) and this guest emitter… CONTINUE READING
