Abstract

유기전자소자는 용액공정을 통한 대량생산이 가능하기 때문에 기존 무기전자소자에 비해 제조비용이 저렴하고 대면적 생산이 가능하며, 유기분자의 본연 특징으로 인해 유연하고 가벼운 소자를 구현할 수 있다. 그러나 무기 반도체에 비하여 현저히 낮은 전하이동도 특성은 유기전자소자의 상용화에 걸림돌이 되고 있다. 따라서 공액고분자의 결정화도, 모폴로지, 분자배향 최적화를 통한 자기조립 박막 제조는 전하이동을 원활히 하기 때문에 유기전자소자의 개발에 필수적이다. 본 기고에서는 유기전자소자의 활성층으로 사용되는 공액고분자의 자기조립을 유도하기 위한 다양한 특성을 갖는 용매 첨가제의 효과에 대해서 알아보고, 특히 첨가제의 용해도 계수가 공액고분자의 자기조립 거동에 미치는 영향에 대해 자세히 논의하고자 한다.
