AB - <p style="text-align: justify;">A novel cyclometalated iridium complex bis[(4-(2-(4-Diphenylamino-phen
yl)-benzoinidazol-1-ylmethyl)-phenyl)-diphenyl-amine]iridium(acetylacetonate) Ir(DBPA)$_2$(acac) 
is designed and synthesized, and the thermo-stability and photo-physical
properties of iridium complex Ir(DBPA)$_2$(acac) are researched in detail. The complex is
functionalized by a bulky non-planarity substituent, thus the phosphorescent concentration
quenching in solid state is substantially suppressed, and Ir(DBPA)$_2$(acac) exhibits
bright green-emitting in both solution and solid. The maximum emission peak
inr pure solid is about 516 nm, which is slightly blue-shifted in comparison with that in
solution. Moreover, the complex Ir(DBPA)$_2$(acac) exhibits high photoluminescent efficiency
and short excited lifetime, indicating it has potential application in fabricating
nodoped electrophosphorescence device.</p>
