A photochromic thin film based on salicylideneaniline derivatives intercalated layered double hydroxide

► Transparent thin films with photochromism ► Co-intercalation of azomethine-H and pentanesulfonate into a layered double hydroxide ► Photochromism of azomethine-H in a 2D confined environment ► Enhanced thermal stability of azomethine-H upon intercalation
