Chiroptical organic semiconductor/chiral molecule hybrid thin-films via chirality transfer phenomenon
Abstract
The key idea of this research is to develop chiroptical conjugated polymer hybrid thin-films by using chirality transfer from the chiral molecules to the achiral organic semiconductor materials. This approach can be important step forward to combine numerous achiral semiconducting polymers, which show good film-forming processability and optoelectronic properties, with various chiral molecules that exist in nature or are readily available. In order to realize this system, fundamental studies on how the chirality of chiral molecules is transferred to achiral semiconductor polymer thin-films will be included. We will systematically investigate the effect of molecular interactions between chiral molecules and achiral conjugated polymers to the self-organization and phase separation behavior, and chiroptical properties of the hybrid film using various chiral molecules under various process condition. Based on this, correlation between the molecular interaction and chirality induction will be elucidated. This work will provide an important basis to develop a practically available chiroptical thin-film from a viewpoint of the material design as well as thin-film process, and contribute to lead further advances in the chiroptical electronic devices and their practical applications.
