Spiral Eu(III) coordination polymers with circularly polarized luminescence

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