Catalysis by flicking a “light switch” is possible with an azobenzene‐based template. When the E isomer of the template is irradiated with light of wavelength 366 nm, the isomeric composition is shifted in favor of the catalytically active Z isomer, and the reaction rate for amide bond formation between modified adenine units is increased by a factor of 10. The light‐induced activation of the template is depicted schematically on the right.
