A new electroluminescent boron compound containing mu-oxo bridge

Abstract

A novel dinuclear boron compound, B-2(O)Ph-2(Meq)(2)(H2OCH2Cl2)-H-.-C-. (Ph = phenyl, Meq = 2-methyl- 8-quinolinolate) was synthesized and characterized. After the investigation of several doping concentrations, the organic electroluminescent (EL) device ITO/PEDOT/PVK + 5 wt% B-2(O)Ph-2(Meq)(2)/LiF/Al (PEDOT = poly(3,4-ethylenedioxythiophene), PVK = poly(N-vinylcarbazole)) was employed to investigate the EL properties. The EL device exhibits blue-green light with maximum luminance of 45 cd/m(2) at 22 V.
