Vapor‐Phase Growth Strategies of Fabricating Organic Crystals for Optoelectronic Applications

Abstract

AbstractVapor‐phase growth methods, taking the advantages of producing high‐quality crystals with low defects, thin thickness, and homogeneous composition, are of great significance in the field of organic crystal growth and their high‐performance applications. At present, the requirements for organic crystals as building blocks for the construction of optoelectronic devices are increasing with the constant advances in organic optoelectronics. Therefore, the vapor‐phase growth method would become one of the practical techniques that cannot be ignored to fabricate organic crystals. In this paper, an overview of different vapor‐phase growth methods for the preparation of organic single crystals is provided. An introduction to the current status of the vapor phase method is presented and the view on the challenges it faces with some promising solution ideas. It is believed that this review will serve as a reference for further development and an inspiration for the new way forward.
