Outline of Final Research Achievements

Circularly polarized luminescence (CPL) of organic molecules has been less explored until recently. We focused in this study on the variety of chiral organic molecules including helical chirality in helicenes, propeller chirality in hexaarylbenzenes, as well as Mobius chirality in expanded porphyrins. Through our systematic investigation, we successfully obtained the structure-property relationship for the chiroptical responses, which can be utilized for design principle for advanced organic CPL materials. Results have been appeared in 36 international original papers. In addition, a relevant review article is under preparation and a book related on CD and CPL on small organic molecules is edited, both of which should be distributed shortly.
