We synthesize π-conjugated polymer based on dihexylfluorene and triphenylamine derivative, which are polyN-(4-(5-(4-tert-butylphenyl)-1,3,4-oxadiazol-2-yl)phenyl)-4-(10-hexyl-3-methyl-10H-phenothiazin-7-yl)-N-p-tolylbenzenamine (TPAOXDPT) and polyN-(4-butylphenyl)-4-(10-hexyl-3-methyl-10H-phenothiazin-7-yl)-N-p-tolylbenzen-amine (TPAPT). The electron transporting unit, conjugated 1,3,4-oxadiazole (OXD), is attached on the main as pendants. In the optical and electrochemical properties, the OXD pendants did not affect PL and EL maximum in comparison with TPAPT. The efficiency of the device based on TPAOXDPT was singnificantly higher than the device based on TPAPT. In this presentation, we will discuss the fundamental optical and EL properties as well as the role of OXD in the improvement of EL efficiency of the polymer. |
