Research Abstract

We designed large artificial molecules that respond to external stimuli, prepared them via organic synthesis, and studied their properties by spectroscopic measurements and molecular simulations. The following progress was made: - We established synthetic strategy for tweezers-like molecules that have two different porphyrins at both ends. - We successfully introduced positive and negative charges at the both ends of the above-mentioned tweezers-like molecules. - We analyzed the behavior of the above molecules in solutions via fluorescence emission spectra, and found that the average conformations were dependent on the bridging part. - We performed computer simulations of the above molecules, and found new design for better observation of the conformational change by external stimuli.
