Outline of Final Research Achievements

Circular polarized light (CPL) has attracted considerable research attention due to its application in fields such as 3D displays, bioimaging, and optical communication systems.
Here we have prepared 2,8-di-tert-butyl-10b,10c-trans-dimetyl- piradino[2,3-e]DHP (PZ-DHP) and its analogs as asymmetric photochromic molecules. The open form of molecules were separated into its constituent enantiomers by chiral HPLC. The absolute structures of the enantiomers were determined by using spectra predicted with time-dependent density functional theory. It shows the photoswitchable circular dichroism properties. These results were reported by two Journals and 7 presentations in intra- and international symposiums.
