Abstract

We report conjugated dendrimers that can be used to fabricate efficient (≤1.0 lm W-1 at ∼100 cd m-2) deep-blue emission (1931 CIE (x, y) ≤ (0.15, 0.10)) and high luminance (≤6000 cd m -2) organic light emitting diodes (OLEDs). Slab waveguide structures of these materials show low amplified spontaneous emission (ASE) thresholds (≥50 nJ for 390 nm, 10 ns, 10 Hz, pulsed excitation). In addition, we report OLEDs based on binary blends of the dendrimers with the green light emitting polymer poly(9, 9-dioctylfluorene-co-benzothiadiazole): these have low turn on voltages (≥2.2 V) and produce high efficiency (18.2 lm W-1 at ∼100 cd m-2) green electroluminescence. © 2007 IOP Publishing Ltd.
