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] triazolyl] iridium (III)-cored dendrimers, bearing first generation 1, 2-diphenylethylene dendrons on the ligand triazolyl and phenyl rings, were prepared in excellent yields, employing ...
