Outline of Final Research Achievements

Chiral organic fluorophores (COFs) emitting circularly polarized luminescence (CPL) with a high quantum efficiency have recently garnered considerable attention in the field of chiral photoluminescence. Generally, to yield a pair of (+) and (-) CPL signals, it is necessary to design a pair of enantiopure COFs with opposite stereogenic centers. However, this approach has several practical limitations, as the preparation of such enantiomers may not always be possible. Herein, we demonstrated that the signs of the CPL and circular dichroism (CD) signals could be reversed by changing the external environment such as solvent.
