Studies of fluorine auxochrome in C9-fluorenyl anthracenes on optoelectronic property for blue electroluminescent materials
Source abstract
Abstract
Abstract Two series of fluorine-containing fluorenyl anthracenes linked by a rigid sp3-hybridized carbon atom have been synthesized and characterized. The effect of a fluorine auxochrome at different positions in fluorene moiety on bulk properties, such as photophysical, electrochemical properties and thermal stabilities were investigated. The non-doped organic light-emitting diodes (OLEDs) utilizing C9-methylated fluorinated fluorenyl anthracene 4b as the emitter exhibits deep-blue emissions CIE x, y (0.159, 0.106) with efficiency of 1.31 cd/A and a maximum brightness of 2040 cd/m2 at 14 V. It was found that the introduction of fluorine auxochrome to the C2 position of fluorene could afford the best performances of OLEDs among the fluorinated materials.
