Spiral Eu(iii) coordination polymers with circularly polarized luminescence

A spiral-type chiral Eu(iii) coordination polymer showed strong luminescence (emission quantum yield phi(f-f) = 57% and photosensitized energy transfer efficiency (sens) = 53%) and effective CD and CPL properties (g(CPL) = 0.17) when compared with a mono-nuclear chiral Eu(iii) complex in the solid state (phi(f-f) = 36%, (sens) = 14%, and g(CPL) = 0.09).
