Abstract

Since organic semiconductor thin films can be fabricated in a large area by a solution process, the organic optoelectronic devices have many advantages in terms of manufacturing costs compared to inorganic electronic devices and light and flexible electronic devices can be implemented, which is suitable for wearable devices due to the soft characteristics of organic molecules. However slow charge transport characteristics and low stability, compared to inorganic semiconductor-based electronic devices, are challenges to the commercialization of organic electronic devices. Many researchers are developing a self-assembled thin film optimized for crystallinity, morphology, and molecular orientation to improve the performance of organic optoelectronic devices. Herein we examine various additives that can induce self-assembly of a conducting polymer used as an active layer in organic optoelectronic devices and examines the effect of additives’ solubility parameter on the self-assembly behavior of conducting polymer and their correlation with the device performance.


유기광전자소자는 유기반도체 박막이 용액공정에 의해 대면적으로 제작이 가능해 무기전자소자와 비교하여 제조 비용측면에서 장점을 지니며, 유기분자의 유연한 특성으로 인해 가볍고 유연한 전자소자를 구현할 수 있어 웨어러블 기기에 적합하다. 하지만 무기반도체 기반의 전자소자에 비해 낮은 전하이동 특성과 낮은 안정성이 유기전자소자의 상용화에 장애물이 되고 있다. 많은 연구자들이 유기광전자소자의 성능향상을 위해서 결정성, 모폴로지, 분자배향이 최적화된 자기조립 박막을 개발하고 있다. 본 논문에서는 유기광전자소자의 활성층으로 이용되는 전도성 고분자의 자기조립을 유도하는 다양한 첨가제에 대해서 살펴보고, 첨가제의 용해도 계수가 전도성 고분자의 자기조립에 미치는 영향과 이에 따른 소자특성과의 상관관계를 살펴보고자 한다.
