Azobenzene-3,3'-dicarboxylic acid exists in photoisomerizable (E) and (Z)-forms. Deprotonation of the carboxylic groups from (E)-form occurs simultaneously, whereas (Z)-form it a stepwise fashion. The mono anionic form (Z)-isomer acts as glycosidase mimic that proceeds through general acid-general base catalytic mechanism. This is first example photoresponsive mimic.
