By cooperative twisting of alternating molecules from the adjacent columns, the structure and the kinetics of the photoinduced nitro-assisted proton transfer of 3-methyl-2-(2',4'-dinitrobenzyl)pyridine can be reversibly gated in a single crystal over a hysteresis gap of 10-11 K close to ambient temperature [1].
