Soft and conformable optoelectronic devices for wearable and implantable electronics require mechanical stretchability. However, very few researches have been done for intrinsically stretchable light-emitting diodes. Here, we present an intrinsically stretchable organic light-emitting diode, whose constituent materials are all highly stretchable. The resulting intrinsically stretchable organic light-emitting diode can emit light when exposed to strains as large as 80%. The turn-on voltage is as low as 8 V, and the maximum luminance, which is a summation of the luminance values from both the anode and cathode sides, is 4400 cd m⁻². It can also survive repeated stretching cycles up to 200 times, and small stretching to 50% is shown to substantially enhance its light-emitting efficiency.

用于可穿戴和可植入电子设备的柔软且舒适的光电设备需要机械拉伸性。但是，对于本征可拉伸的发光二极管仅进行了很少的研究。在这里，我们介绍了一种本质上可拉伸的有机发光二极管，其组成材料都具有很高的可拉伸性。当暴露于高达80％的应变时，所得的固有可拉伸的有机发光二极管可以发光。导通电压低至8 V，最大亮度为4400 cd m ^-2，最大亮度是来自阳极和阴极侧的亮度值的总和。它也可以经受多达200次的重复拉伸循环，并且显示出小幅拉伸至50％可以显着提高其发光效率。
