摘要
A novel p-type charge generation material, DPAF, composed of a ferrocene core and a bis(biphenyl) amino group is designed and synthesized for application to tandem OLED devices. This molecular design not only enhances the thermal properties of ferrocene and the hole mobility, but also maintains its electrochemical stability. The red, green, and blue tandem OLEDs all give excellent device performance with low efficiency roll-off by using n-type C-60 and p-type DPAFs as charge generation layers.
