Abstract
AbstractDithienylethene (DTE)‐embedded expanded porphyrins were synthesized and confirmed to be photochemically inactive due to the lowest excited state of the expanded porphyrins. On the other hand, DTE‐embedded expanded calixphyrins exhibited reversible photochromism upon UV‐irradiation to form colored closed forms, which reverted to colorless open forms upon red‐light irradiation. The closed forms were oxidized with DDQ or the air to lock the recorded information by converting to photochemically inactive expanded porphyrins. This was unlocked by reduction with NaBH4 to restore expanded calixphyrins with photochromism activity. These gated photochromic behaviors were demonstrated in PMMA (polymethyl methacrylate) film.
