초록
수면 위의 지질 단분자는 박막 모델로서 많은 관심을 끌고 있으며, 많은 기술적인 응용법에 의해 다층의 박막 시스템을 연구하고 있다. 아조벤젠 혼합물인 아조벤젠 덴드리머의 단분자막에서 광이성화는 흡수스펙트럼과 멕스웰 변위전류법(MDC)에 의해 관찰할 수 있다. 덴드리머는 나뭇가지 모양을 닮은 고분자이며, 흡수스펙트럼에 의해 trans-to-cis 변환을 평가할 수 있다. 본 연구에서는 덴드리머의 광이성화특성에 관하여 연구하였다.
Monolayers of lipids on a water surface have attracted much interest as models of thin films, also as precursors of multilayer systems promising many technical applications. Photoisomerization in monolayers of a novel azobenzene compound, azobenzene dendrimer, was investigated for the first time by means of the absorption spectrum and Maxwell displacement current (MDC) technique. Dendrimers are well-defined macromolecules exhibiting a tree-like structure, first derived by the cascade molecule approach. According to the absorption spectrum, trans-to-cis conversion ratio was estimated to azobenzene dendrimer deposited onto a glass substrate. As a result, It's photoisomerization progressed by dendrimer.
