Abstract
We previously reported the synthesis of an insoluble distyrylbenzene (DSB) derivative and its promising results in the fabrication of organic light-emitting devices. In this work, we report the design, synthesis and characterisation of two soluble alkoxysubstituted distyrylbenzenes, one symmetrical and one unsymmetrical. Using the Langmuir-Blodgett (LB) technique, we successfully deposited 35 layers of one of our most promising distyrylbenzene derivatives on indium-tin oxide (ITO)-coated glass substrate, with aluminium forming the top contact to form a single-layer (SL) electroluminescent (EL) device. The I-V characteristics for such a device operated under forward bias is similar to a semi-classical rectifying diode and the onset of visible light emission occurs around 5 V. © 2002 Elsevier Science B.V.
