基于电解质的发光器件，如发光电化学电池（LECs）和双层电晶体管（edlt），是一种结构非常简单的溶液可加工器件。因此，有必要将这种器件结构应用于高荧光有机材料中，以用于未来的印刷应用。然而，由于电解质与有机晶体之间的相容性问题，基于电解质的单晶发光器件尚未得到证实。在这里，我们报告了基于有机单晶和电解质的发光器件。荧光材料选用α，ω-双（联苯基）噻吩（BP3T）和5,6,11,12-四苯基萘（rubrene）单晶。使用离子液体作为电解质，我们观察到BP3T电子发光管和rubrene电子发光管的清晰发光。
Light-emitting devices based on electrolytes, such as light-emitting electrochemical cells (LECs) and electric double-layer transistors (EDLTs), are solution-processable devices with a very simple structure. Therefore, it is necessary to apply this device structure into highly fluorescent organic materials for future printed applications. However, owing to compatibility problems between electrolytes and organic crystals, electrolyte-based single-crystal light-emitting devices have not yet been demonstrated. Here, we report on light-emitting devices based on organic single crystals and electrolytes. As the fluorescent materials, α,ω-bis(biphenylyl)terthiophene (BP3T) and 5,6,11,12-tetraphenylnaphthacene (rubrene) single crystals were selected. Using ionic liquids as electrolytes, we observed clear light emission from BP3T LECs and rubrene EDLTs.
