Organic semiconductors may be processed from fluids using graphical arts printing and patterning techniques to create complex circuitry. Because organic semiconductors are weak van der Waals solids, the creation of glassy phases during processing is quite common. Because structural disorder leads to electronic disorder, it is necessary to understand these phases to optimize and control the electronic properties of these materials. Here we review the significance of glassy phases in organic semiconductors. We examine challenges in the measurement of the glass transition temperature and the accurate classification of phases in these relatively rigid materials. Device implications of glassy phases are discussed. Processing schemes that are grounded in the principles of glass physics and sound glass transition temperature measurement will more quickly achieve desired structure and electronic characteristics, accelerating the exciting progress of organic semiconductor technology development.

可以使用图形艺术印刷和图案化技术从流体中加工有机半导体，以创建复杂的电路。因为有机半导体是弱范德华固体，所以在加工过程中产生玻璃相是很常见的。由于结构无序导致电子无序，因此有必要了解这些相以优化和控制这些材料的电子特性。在这里，我们回顾了有机半导体中玻璃相的重要性。我们研究了玻璃化转变温度测量和这些相对刚性材料中相的准确分类方面的挑战。讨论了玻璃相的器件含义。
