Abstract | Back and forth motions of the acid-base-operated molecular switch 1 are photo-controlled by irradiation of a solution, which also contains the photolabile pre-fuel 4. The photo-stimulated deprotection of the pre-fuel produces controlled amounts of acid 2, the base-promoted decarboxylation of which fuels the back and forth motions of the Sauvage-type [2]-catenane-based molecular switch. Because switch 1 and pre-fuel 4 do not interact in the absence of irradiation, an excess of the latter with respect to 1 can be added to the solution from the beginning. In principle, photocontrol of the back and forth motions of any molecular machine, the operation of which is guided by protonation/deprotonation, could be attained by use of pre-fuel 4, or of any other protected acid that undergoes deprotection by irradiation with light at a proper wavelength, followed by decarboxylation under conveniently mild conditions. |
