Organic semiconductors offer great promise through their ease of synthesis in a multitude of derivatives, their low temperature processability and their amenability for fabrication of flexible, stretchable and conformable, even imperceptible devices. Nevertheless, the low charge mobility of organic semiconductors remains one of the limiting factors in delivering high performance for organic electronic devices comparable to their inorganic counterparts. In this study, the effects of purification of eight different organic semiconductors (i.e. n-type, p-type, and ambipolar) were determined by means of analyzing their performance improvement in organic field effect transistors. For this purpose, three purity grades of each organic semiconductor were investigated, and devices were fabricated in an identical fashion. It was found that temperature gradient sublimation improves considerably the quality of the organic semiconductors. The results presented here indicate that the purity of the organic semiconductor is a key parameter to be considered in order to achieve high performance for the field of organic field effect transistors.

有机半导体的纯度是影响有机电子设备性能的关键因素

有机半导体通过其易于合成的多种衍生物，其低温可加工性以及其对制造柔性，可拉伸和适形甚至不可感知的器件的适应性而提供了广阔的前景。然而，有机半导体的低电荷迁移率仍然是与无机同类产品相比可为有机电子设备提供高性能的限制因素之一。在这项研究中，纯化八种不同有机半导体（即通过分析有机场效应晶体管的性能改善来确定n型，p型和双极性）。为此，研究了每种有机半导体的三个纯度等级，并以相同的方式制造器件。发现温度梯度升华大大改善了有机半导体的质量。此处给出的结果表明，有机半导体的纯度是要在有机场效应晶体管领域实现高性能所需考虑的关键参数。
