Efficient blue fluorescent organic light-emitting diodes based on novel 9,10-diphenyl-anthracene derivatives
A series of novel 9,10-di(naphthalen-2-yl)anthracene (ADN) derivatives were designed and synthesized as blue fluorescent emissive materials by inducing diverse aromatic groups to the C-2 position of ADN. UV-Vis absorption, fluorescence emission spectroscopy and cyclic voltammetry (CV) were carried o...

Summary: | A series of novel 9,10-di(naphthalen-2-yl)anthracene (ADN) derivatives were designed and synthesized as blue fluorescent emissive materials by inducing diverse aromatic groups to the C-2 position of ADN. UV-Vis absorption, fluorescence emission spectroscopy and cyclic voltammetry (CV) were carried out to generally investigate the relationships between the physical properties and molecular structures. Moreover, four non-doped OLED devices adopting
OCADN
,
FA3PADN
,
FA4PADN
and
OC4PADN
as emitting materials were fabricated to study their electroluminescence (EL) performances. Among them, a device based on
OCADN
exhibited highly efficient sky-blue emission with a current efficiency of 2.25 cd A
−1
, power efficiency of 1.13 lm W
−1
and CIE(

) coordinate of (0.16, 0.30) at 8 V. In addition, the device of
OC4PADN
showed efficient blue emission with a CIE(
x
,
y
) coordinate of (0.16, 0.14) at 8 V. |
