Abstract
Disclosed are an amine-oxide-group-containing conjugated polymer photoelectric material and application thereof. The amine-oxide-group-containing conjugated polymer photoelectric material consists of conjugated main chains and a side chain containing an amine oxide unit, and is applied in an organic photoelectric device. The material has desirable alcohol/water solubility and photoelectric properties, is suitable for making a multi-layer solution for machining a device, and meanwhile can prevent an adverse effect incurred by freely moving counter ions in a common polyelectrolyte to the device. The material may be used as a cathode interface modification layer applied in organic photoelectric devices such as light-emitting and photovoltaic devices, so as to improve performance of the devices.
