What is Effect of Amphiphilic Copolymer Containing Ruthenium Tris(bipyridyl) Photosensitizer on the Formation of Honeycomb-patterned Film about?

A new functional amphiphilic polymer (A P ) containing ruthenium tris(bipyridyl) photosensitizer was synthesized and a honeycomb-patterned film was fabricated by casting a polystyrene solution and different concentrations of A P under humid conditions. The amphiphilic copolymer was obtained by the radical copolymerization of ruthenium (4-vinyl-4 0 -methyl-2,2 0 -bipyridine)bis(2,2 0 -bipyridine)bis(hexaflurophosphate) with N-dodecylacrylamide and N-isopropylacrylamide. Without the addition of A P , irregularly ordered porous films were obtained, while adding A P in the casting solution resulted in highly ordered honeycomb-patterned films. In addition, the pore diameter and height of the porous structure increased with the increase of A P amount in the solution. However, an excessive amount of A P induced an irregularly structured pattern with small pore sizes.
