    Abstract: 본 발명은 분자 소자용 π-공액성 화합물에 관한 것으로서, 더욱 상세하게는 자기 조립이 가능하고 전체 분자가 π-공액 결합으로 연결되어 전자 비편재화가 용이한 구조를 가지며, 또한 분자 내에 양이온을 포함하고 있어 산화/환원이 가능하여 외부에서 가해준 전기장에 의해 용이하게 전자를 트랩할 수 있는 성질을 갖으며, 말단에는 금 전극 혹은 기타 금속 전극과 반응하여 단분자 막을 용이하게 형성하는 티올기 혹은 티올기의 전구체 혹은 티올기와 유사 반응성기를 가지고 있어 고집적화된 전자 소자의 제조에 유용한 π-공액성 화합물에 관한 것이다.
    금(Au) 전극 상에 형성된 단분자 박막이 외부에서 가해준 전기장에 의해 전자의 이동을 제어할 수 있으면, 이 단분자막은 분자 다이오드, 분자 트랜지스터 및 분자 스위치 등에 응용될 수 있음이 최근 발표되고 있다. 현재 이와 같은 용도로 잘 알려진 분자는 분자 내에 니트로기와 같은 전자받게(electron acceptor)기가 있어 쉽게 전자를 분자 내에 트랩할 수 있는 구조를 가진다. 본 발명의 목적은 전자받게기로 니트로기 대신에 양이온기를 도입시켜 또 다른 방법으로 분자의 산화/환원이 일어날 수 있는 화합물을 제공하는 것이다.
