Abstract

The emission and conductivity of a new polymer poly (9,9-dioctylfluorenyl- 2,7-diyl) end capped with polyhedral oligomeric silsesquioxanes (PFO-POSS) have been investigated by the differential approach. Thin films of PFO-POSS showed pure blue photoluminescence (PL) with structured spectrum and a maximum at PL=423nm. However, the OLED structures formed on the PFO-POSS base emitted green light with broadened spectrum and a maximum at EL=510 529nm. The electroconductivity and electroluminescence have shown that the greatest influence on the current voltage and luminance current characteristics is rendered by introducing the electron transport layer to the multilayer OLED structure under investigation.
