초록

We synthesized dendrimers containing light switchable units such as azobenzene group at the air/water interface. Their chemical structure was verified by using NMR study and UV spectroscopy. We firstly investigated the monolayer behavior and by light irradiation using $\pi$-A isotherm at the air/water interface. As a result, the monolayer of dendrimer with azobenzene group showed the reversible photo-switching behavior by the isomerization of azobenzene group in their periphery. This suggests that optical behavior and morphological change are affected by the functional group and the symmetric chain.
