The Distance Dependence of Photoluminescence in Electroactive Organics
Research into electroactive organics has increased as organic light emitting diodes (OLEDs) have begun to be incorporated into commercial devices. For example; displays for digital cameras, some electric shavers and a few automobiles have been produced already. Much remains to be learned however, about the structure/property relationships that govern performance of electroactive organics. My research is based on one of these parameters - The interchain distance dependence of the device efficiency. For this purpose a poly(phenylenevinylene) (PPV) derivative oligomer with an oxadiazole moiety is being synthesized. By attaching the oxa-PPV oligomers to helical peptides with well defined structures that are prepared in the Kiick lab, we will be able to determine the potential effect of distance on photoluminescence efficiency of the oligomers.
