Brominated Pyrrole‐Hemithioindigos and Pyrrole‐Hemioxyindigos
ChemPhotoChemHemithioindigos (HTIs) have become a well‐established representative in the toolbox of photoswitches; their pyrrole variants exhibit particularly beneficial properties. The oxy‐analogues of HTIs, namely hemioxyindigos (HOIs) or aurones, have so far been underrepresented as photoswitches; up until now, only a single pyrrole‐HOI had been described in the
