초록

트리아진(triazine) 코어를 중심으로 아조벤젠을 말단기로 갖는 광 감응성 화합물을 합성하고, 초분자 구조체를 제조하여 용매에 따른 구조적 특성을 조사하였다. 트리아진 유도체 N2,N4,N6-tris(4-((E)-phenyldiazenyl) phenyl)-1,3,5-triazine-2,4,6-tricarboxamide(Azo-TA)를 디메틸설폭사이드와 디메틸포름아마이드 용매에 녹인 후, 증류수를 첨가해 섬유상의 초분자 고분자구조체를 만들었다. 아조벤젠의 광이성질화에 의해, 365 nm 파장의 자외선을 조사하면 초분자 구조의 분해가 일어나고, 400 nm 파장 이상의 가시광선을 조사하면 초분자 구조의 재조립이 일어나는 것을 확인하였다.

A photoresponsive azobenzene derivative having a triazine core moiety was prepared. Self-assembly of the triazine containing azobenzene derivative (Azo-TA) in aqueous dimethylsulfoxide and N,N-dimethylformamide afforded fibrous supramolecular polymers. Melting and regeneration of the supramolecular polymer were observed with alternative 365 nm UV and visible light irradiation by reversible cis-trans isomerization of azobenzene moieties.

Keywords:triazine;azobenzene;photoisomerization;phase transition;supramolecular structure
