Tsai et al. (2) determined that blue phosphorescent organic light-emitting devices consisting of 2,2 -bis(A,A-disubstituted amino)-9,9 -spirobifluorenes, (I), were effective as hole transporting materials and had efficiencies of up to 16%, 30.6 cd/A and 26.7 lm/W. 

Metal complexes with Schiff base ligands have useful applications in organic optoelectronics due to their outstanding photoluminescent (PL) and electroluminescent (EL) properties, and their ease of synthesis, which readily allows structural modification for optimization of material properties.28 Hamada and co-workers pioneered the use of zinc(II) Schiff base complexes as blue to greenish white emitters for EL devices. We have demonstrated Pt(II) Schiff base triplet emitters as yellow dopants for organic light-emitting devices... 

Fuji [3] prepared a five-component, (IV) - (VIII), organic light-emitting device that emitted a spectral component in the wavelength range of blue or shorter.

After the application of conjugated polymers as organic semiconductors in light-emitting devices has been demonstrated,49,50 poly(para-phcnylcne) (PPP) was the first simple conjugated polymer to produce visible blue light emission when used as an active layer in polymer LEDs.51...
