Solution-processible saturated blue phosphorescence is an important goal for organic light-emitting diodes (OLEDs). Fac-tris(5-aryltriazolyl)iridium(III) complexes can emit blue phosphorescence at room temperature. Mono- and doubly dendronized fac-tr

By using phosphorescent emitters, organic light emitting displays can be up to four times more efficient than those of fluorescent materials. Full colour displays based on phosphorescent materials have not been achieved thus far due to the poor effic

We report a new family of homoleptic iridium(III) complexes that emit blue phosphorescence at room temperature. The iridium( III) complexes are comprised of phenyltriazole ligands and were easily prepared via short synthetic routes. The parent fac-tr

Solution-processable blue phosphorescent emitters with high luminescence efficiency are highly desirable for large-area displays and lighting applications. This report shows that when a fac-tris[1-methyl-5-(4-fluorophenyl)-3-n-propyl-1H-[1,2,4]triazo

Organic light-emitting diodes (OLEDs) have great potential for displays and lighting applications. For large area displays the ideal materials would be both phosphorescent and solution processible. These requirements mean that the materials need to b

A simple convergent procedure, involving the Diels-Alder reaction between 2,3,4,5-tetraphenylcyclopentadienone with an acetylene-substituted 2-phenylpyridine and subsequent complexation with iridium(III), has been developed for the formation of highl

New high triplet energy dendrons based on 1,2-diphenylethylene with and without 2-ethylhexyloxy surface groups have been developed for deep blue phosphorescent iridium(III) dendrimers. The fac-tris[1-methyl-5-(4-fluoro)phenyl-3-n-propyl-1H-[1,2,4]tri

A convergent strategy for the synthesis of three generations of dendrons comprised of carbazole moieties is described. The procedure to build the dendrons involves an iterative palladium catalysed amination–debenzylation sequence using N-benzyl-3,6

A family of (1,10-phenanthroline)rhenium(I)(CO)3Cl complex cored first generation dendrimers with one, two or three dendrons have been prepared. The first generation dendrons attached to the core complex are comprised of biphenyl units with 2-ethylhe
