Acidic pH Modulated Photoswitching of Sulfur-bridged Seven-membered Cyclic Azopyridines

Azoarene molecular photoswitches with bistability are a family of widely employed structure-tuning units for photopharmacology and smart material construction. Notably, medium-ring azobenzenes, especially seven-membered dibenzo[ b , f ][1,4,5]thiadiazepines (DBTD), are characterized as fast-responsive...
