An appealing supramolecular system design strategy has been adopted to control photo-reduction in a novel supramolecular way. An aromatic photo-sensitive core was used to synthesize two different sets of appropriate ionic aromatic amphiphiles. They can selectively be photo-reduced to generate different redox states in the presence of dicarboxylic acids as counter anion (CA). Interestingly, we found an exhibition of fluorescence switching in the different redox states. The reduction mechanisms and the kinetics were found different and that was further controlled by the structurally different CAs. This unexpected observation has been portrayed as characteristic molecular recognition manner in the controlled assembly systems. The changes in spectroscopic output upon an electronic input have been described as a simple 'OFF/ON' FL switching with an appealing 'bottom-up' approach toward molecular device fabrication that is possible only in the molecular assembly systems. |
