A rod-coil block copolymer consisting of poly(3-hexylthiophene) (P3HT) and poly(N-vinylcarbazole) (PVK) (P3HT-b-PVK) in a single molecular architecture is prepared as the first example for WOLEDs. By obtaining the phase separated domains in thin film of the resulting block copolymer, it is possible to suppress energy transfer from PVK as wide bandgap units to P3HT as low bandgap blocks, yielding dual emissions for white electroluminescence with CIE coordination of (0.34, 0.33).
制备了一种由聚（3-己基噻吩）（P3HT）和聚（N-乙烯基咔唑）（PVK）组成的棒-线圈嵌段共聚物（P3HT-b-PVK），其具有单一分子结构，作为用于白色有机发光二极管（WOLED）的首个实例。通过在所得嵌段共聚物的薄膜中获得相分离域，能够抑制从作为宽带隙单元的PVK到作为低带隙嵌段的P3HT的能量转移，从而产生用于白色电致发光的双发射，其CIE坐标为（0.34, 0.33）。
