A novel triphenylamine-substituted and fully conjugated poly(1,4-phenylenevinylene), poly[5-(4′-(N,N-diphenylamino)-phenyl)-2- (2′-ethylhexyloxy)-1,4-phenylenevinylene-alt-5-methoxy-2- (2′-ethylhexyloxy)-1,4-phenylenevinylene] was synthesized by Wittig-Horner-type polycondensation. The polymer gave a high photoluminescence efficiency as a film (31%) and a low ionization potential of -5.1 eV. The simple double-layer light-emitting-diode devices of the polymer exhibited a very high luminance of 29 500 cd/m2 under a low driving voltage (≈8 V).
