Sugar-controlled association and photoinduced electron transfer in boronic-acid-appended porphyrins

Complexation–decomplexation equilibria between boronic-acid-appended porphyrins and naphthalenedisulfonates or anthraquinonedisulfonates can be efficiently controlled by the addition of saccharides: this finding is readily applied to the saccharide-controi of photoinduced electron-transfer processes.
