Beschreibung
Zusammenfassung:An organic optoelectronic device comprises a first electrode, an active layer and a second electrode. Active layer materials of the active layer comprise a block conjugated polymer materials which includes a structure of formula I:The polymer 1 is a p-type polymer with high energy gap, and the polymer 1 comprises a first electron donor and a first electron acceptor arranged alternately. The polymer 2 is a p-type polymer with low energy gap, and the polymer 2 comprises a second electron donor and a second electron acceptor arranged alternately. Wherein, o and p>0. The organic optoelectronic device of the present invention transfers carriers through the polymer 2 with low energy gap, and suppresses the recombination probability of carriers through the polymer 1 with high energy gap, thereby reducing the leakage current of the organic optoelectronic device.
