文摘
In this article, we describe the fabrication of azobenzene-containing supramolecular side-chain polymerfilms based on hydrogen bonds, on which surface relief gratings can be laser-induced. The supramolecularpolymer side-chain is formed by attaching different azobenzene-type compounds to poly(4-vinylpyridine)through hydrogen bonding, thus allowing for tuning the content and kind of the azobenzene derivativeseasily and avoiding the tedious synthetic work. It is found that such an azobenzene-containingsupramolecular side-chain polymer can form nice films by the spin-coating method for surface reliefgratings, and moreover, a large surface modulation depth of 312 nm can be observed. We anticipate thatthis research provides a type of materials for surface relief gratings. In closing, we have provided a newapproach for fabricating surface relief gratings employing hydrogen-bonded supramolecular side-chainazo polymers.
