We have prepared and characterized polymer light-emitting electrochemical cells (LECs) containing a binary mixture of the conjugated polymer poly[2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylenevinylene] and the ionic liquid 1-ethyl-3-methylimidazolium ethylsulfate as the active material. We demonstrate, for the first time, that it is possible to turn on and attain light emission from LECs, with a mm-sized interelectrode gap separating two identical Au electrodes, at a low voltage of 3 V and at room temperature.
我们制备并表征了聚合物发光电化学电池（LEC），其包含共轭聚合物聚[2-甲氧基-5-(2'-乙基己氧基)-1,4-亚苯基亚乙烯基]和离子液体1-乙基-3-甲基咪唑硫酸乙酯的二元混合物作为活性材料。我们首次证明，在室温下，以3V的低电压，能够使两个相同的金电极之间具有毫米级电极间隙的LEC开启并实现发光。
