Template effects of metal ions on photodimerization of bis-1-anthracenecarboxamide linked by the oxyethylene chain

Template effects and supramolecular control of photoreactions in solution

“…In the example reported by Nakamura and co-workers, the anthracenes are joined through the C-1 or C-2 position, which leads to the formation of chiral photoproducts. 177,178 The C-1 linked system was shown to be sensitive to both monovalent and divalent alkali metal ions, whereas the photoreactivity of the C-2 linked system proved to be relatively insensitive to metal ions. By combining binding sites adapted for different metal ions, Desvergne, Tucker, and co-workers constructed an assembly that is sensitive to the presence of two orthogonal stimuli (compound 18, Fig.…”

Template Effects of Metal Cations for Controlling the Regioisomer Distribution on the Photodimerization of N,N′‐Linked Bis(anthracenecarboxamides)

“…On the basis of this idea, we preliminarily reported on the photoreaction of 1. [44] In this paper, we report the results of the intramolecular photodimerization of 1 and 2, and the quantitative effect of metal cations on the photoreaction. Changes to the conformation of the 1·metal cation complex in the ground state that influence the photoproduct ratio are also discussed.…”
