摘要

1.Introduction Rubrene, as a tetraphenyl derivative of tetracene,with a π-conjugated structure,has been intensively studied for use as a doping layer for OLEDs and as an active material for OFETs.The hole transport property of the rubrene single crystal is excellent because of the relatively strong π-π overlap of the rubrene molecules. The rubrene single crystal based OFETs showed p-type characteristics and a field-effect mobility of about 20 cm2/Vs,which is higher than that of other OFETs made from anthracene, tetracene, and pentacene molecules. In this study,we report a new method for the fabrication of homogeneous light emitting nanowires array of organic semiconducting rubrene molecules.Photoluminescence (PL) spectra including laser confocal microscope (LCM) PL spectra in nanometer scale of the rubrene nanowires were compared with those of rubrene single crystals.We observed that LCM PL spectra and intensity of rubrene nanowire and its single crystal in the nanometer scale,because of crystal growth characteristics of the rubrene molecules.A single rubrene nanowire had the wider PL band width than that of rubrene single crystal,which might have originated from the light emission of the mixed polarized bands due to the additional new crystallinity in the form of nanowires.The hybrid ruhrene nanowire attached Au nanoparticles were also compared with those of the rubrene nanowire through LCM PL spectra.The electrical conductivity (σDC) of a single strand of rubrene nanowire was also estimated to be～1.0×10-4 S/cm.
