Photoinduced proton transfer systems such as 2‐(2′,4′‐dinitrobenzyl)pyridine derivatives have been developed in an attempt to apply the compounds to variable optical transmission materials. However their fatigue resistance property is a limitation for these applications. New benzylpyridines have been synthesized and tested. 2‐(2′,4′‐Diphenylsulfonybenzyl)pyridine was found to be photochromic in the crystalline state and in ethanolic solution (λ max = 485 nm) upon UV flash photolysis.
