Abstract
AbstractHerein, we describe water‐soluble heteroaryl azopyridinium ionic photoswitches (HAPIPs). We aim to combine variations in five‐membered heterocycles, their substitutions, N‐alkyl groups at pyridinium nitrogen, the position of pyridinium center relative to azo group, counterions, and solvents, in achieving better photoswitching. Through these studies, we successfully tuned the half‐life of Z isomers of the resultant HAPIPs between seconds to days in water. Extensive spectroscopic studies and density functional theory (DFT) computations unravelled the factors responsible for thermal relaxation behavior. Considering the versatility of these photoswitches, the tunability of half‐lives and photoswitching in aqueous medium allows the scope of applications in several fields.
