Orientation dependence of chiral light-conjugated molecule interactions in chiroptical thin films with supramolecular structure of pi -conjugated molecules
Abstract
The key idea of this research is to systematically investigate the orientation dependence of the supramolecular structure of chiral pi -conjugated molecules on the chiroptical activity, aiming to provide fundamental insight into the chiral light-conjugated molecule interactions. This study will contribute to a comprehensive understanding of structure-property relationships of chiral pi -conjugated molecules encompassing from intrinsic molecular state to supramolecular structure in the interaction with chiral light. To conduct this study, a directional orientation control of chiroptical supramolecular structure will be demonstrated through self-assembly of pi -conjugated molecules within a confined geometry. The chiroptical supramolecular structure of pi -conjugated molecules with different uniaxial alignment directions will be controlled by varying confined geometry and self-assembly conditions. Through in-depth study for the structural and spectroscopic analysis of these aligned supramolecular structures, we will try to reasonably interpret the electronic and magnetic transition moments induced by chiral light interaction, giving a direct foundation for understanding the mechanism of chiroptical activity in supramolecular assembly of pi -conjugated molecules.
