Poly(3-heptylpyrrole) was demonstrated to serve as an efficient π-conjugated ligand to afford a conjugated complex with Pd(MeCN)2Cl2, which was successfully applied to organic light emitting diode (OLED) devices. An OLED device with the conjugated complex film as a hole injection layer performed the maximum luminance of 11,000 cd/m2at 10 V, which was 2 V lower than a device with the conventional copper phthalocyanine (CuPc) hole injection layer. © 2006 Elsevier B.V.
