Abstract

We found that a phenylene ethynylene derivative, 1,4-bis(4-(phenylethynyl) phenylethynyl)benzene (BPPB), provides very high photoluminescence efficiency both in solution (Φ_PL = 95 ± 3%) and thin films (Φ_PL = 71 ± 3%); further, we observed blue electroluminescence (EL) of λ_{EL (max)} ∼470 and 510 nm with an external EL efficiency of η_EL ∼0.53% and maximum luminance of ∼70000 cd m^-2 at current density of ∼2 A cm ^-2 with BPPB as an emitter; also we identified that BPPB functions as a hole transport layer in organic light emitting diodes.
