  • PLANAR CONJUGATED COMPOUNDS AND THEIR APPLICATIONS FOR ORGANIC ELECTRONICS
    Publication number: 20110303909
    Abstract: The invention relates to organic semiconducting materials, methods for their preparation and organic electronic devices incorporating the said organic semiconducting materials. The organic semiconductors contain a compound of formula (I) Ar1=(Qu)m=Ar2??(I) where Qu is independently a substituted or unsubstituted, substantially planar 5 to 8 membered conjugated ring, and Ar1 and Ar2 each independently is a substituted or unsubstituted, substantially planar conjugated aromatic structure having from 5 to 50 carbon atoms. The compounds of formula may generally form an H-shaped molecular structure. The said organic semiconducting materials could be used as the active layers for organic electronic devices, e.g. thin film transistors, photovoltaic cells, photo detectors, light emitting diodes, memory cells, sensors etc.
