Abstract
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.
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.
