SBIR Phase I: Chiropticenes: Molecular Chiroptical Dipole Switches

点击翻译按钮获取中文摘要

This Small Business Innovation Research Phase I project is based on the development andcommercialization of Chiropticenes, a novel class of single-molecule chiroptical dipole switches. Chiropticene molecular switches are triggered by a combination of light and electric field, which cause both the chirality and dipole direction to be reversed. Information stored in the Chiropticenes is read nondestructively with circularly polarized light, which ensures erase-read-write capability. The Chiropticene molecular switch is the fundamental component in CALMEC's nanotechnology-based optical data storage technology.The objective of the Phase I research is to demonstrate the feasibility of the uniqueChiropticene switch. Various organic Chiropticenes will be synthesized, characterized andthen 'switched' using a combination of electric field and light. The completion of PhaseI will verify the switch mechanism and lead directly into Phase II, which is thefabrication of a two-dimensional optical data storage device.
