Circularly polarized luminescence from open- and closed-style axially chiral amphipathic binaphthyl fluorophores in water

Circularly polarized luminescence from open- and closed-style axially chiral amphipathic binaphthyl fluorophores in water
Chiral, ionic C 2-symmetric binaphthyl fluorophores with amphipathic property can emit circularly polarized luminescence (CPL) in the near-UV region when dissolved in either water or methanol. Despite the same axial chirality (R or S) of the binaphthyl units, the open- and closed-style fluorophores induced sign inversion of CPL and circular dichroism (CD) signals in water. The dihedral angle of the binaphthyl C 2-axis appears to determine the signs of CPL and CD signals even in water.
