Rapid advances in research and development in organic electronics have resulted in many exciting discoveries and applications, including organic light-emitting devices for information display and illumination, solar cells, photodetectors, chemosensors, and logic. Organic optoelectronic materials are broadly classified as polymeric or small molecular. For the latter category, solvent-free deposition techniques are generally preferred to form well-defined interfaces and improve device performance. This article reviews several deposition and patterning methods for small molecular thin films and devices, including organic molecular beam deposition, vacuum thermal evaporation, organic vapor phase deposition, and organic vapor jet printing, and compares them to several other methods that have been proposed recently. We hope this review provides a compact but informative summary of the state of the art in organic device processing and addresses the various techniques' governing physical principles.
有机电子学在研究和开发方面的快速进展带来了许多令人兴奋的发现和应用，包括用于信息显示和照明的有机发光器件、太阳能电池、光电探测器、化学传感器和逻辑器件。有机光电材料通常被广泛地分为聚合物或小分子。对于后者类别，通常优选使用无溶剂沉积技术来形成良好定义的界面并改善器件性能。本文综述了几种小分子薄膜和器件的沉积和图案化方法，包括有机分子束沉积、真空热蒸发、有机气相沉积和有机气相喷射印刷，并将它们与最近提出的几种其他方法进行了比较。我们希望这篇综述能提供有机器件处理方面的最新技术的简明但信息丰富的概述，并介绍各种技术的主要物理原理。
