Dibenzothiophene, dibenzofuran and pyridine substituted tetraphenyl silicon derivatives hosts for green phosphorescent organic light-emitting diodes

We report the application of four novel tetraphenyl silicon derivatives as host materials in phosphorescent organic light-emitting diodes (PHOLEDs). The novel derivatives are; 3-(4-((4-(dibenzo[b,d]thiophen-4-yl)phenyl)diphenylsilyl)- phenyl)pyridine (DBTSiPy3), 4-(4- ((4-(dibenzo[b,d]thiophen-4-yl)phenyl)diphenyl- silyl)phenyl)pyridine (DBTSiPy4), 3-(4-((4-(dibenzo[b,d]furan-4-yl)phenyl)- diphenylsilyl)phenyl)pyridine (DBFSiPy3) and 4-(4-((4-(dibenzo[b,d]furan-4- yl)phenyl)diphenylsilyl)phenyl)pyridine (DBFSiPy4). They were prepared by the introduction dibenzothiophene (DBT)/dibenzofuran (DBF) and pyridine units into bis(4-bromophenyl)diphenylsilane intermediate. The influences of DBT/DBF and the position of nitrogen atom within the pyridine unit (3- vs 4-position) were studied by theoretical calculations and experimental measurements. To evaluate the electroluminescent (EL) performance of these four materials, (2-phenylpyridine) iridium(III) (Ir(ppy)3) based green PHOLEDs were fabricated using the common device structures. DBF substituted materials (DBFSiPy3 and DBFSiPy4) led to efficient green PHOLEDs with notable external quantum efficiencies (EQE) of 22.9% and 21.9% respectively.

HOST MATERIALS FOR OLEDS

Novel aryl silicon and aryl germanium host materials are described. These compounds improve OLED device performance when used as hosts in the emissive layer of the OLED.
