Right-/left-handed helical G-quartet nanostructures with full-color and energy transfer circularly polarized luminescence

Abstract

Right (R)- and left (L)-handed helical G-quartet nanostructures were synthesized for the first time simultaneously via the self-assembly of 5′-guanosine monophosphate (GMP), the helical handedness of which is well regulated by metal ions. These g-nanostructures were further applied as circularly polarized luminescence (CPL) templates to realize full-color R-/L-CPL and Förster resonance energy transfer CPL. The g_lum value reached 10⁻², indicating their excellent template function for CPL materials design and application.
