| Abstract: | The Schiff-base ligand boron complex, LBF2 L=ortho-C6H4(NC6H3Me2-2,6)(CH=NC6H3Me2-2,6)], is synthesized and characterized. The crystal structural study reveals that central boron atom is four coordinate and adopts a distorted tetrahedral geometry in LBF2. The photo/electroluminescent properties of the boron complex have been studied. The electroluminescent devices were fabricated by doping LBF2 in polymer blends host of poly(vinylcarbazole) (PVK) and 2-tert-butylphenyl-5-biphenyl-1,3,4-oxadiazol (PBD) using simple solution spin-coating technique. The single-layer polymer organic light emitter devices exhibited blue-green emission with maximum current efficiency of 1.6 cd/A and maximum luminance of 840 cd/m2. |
