Solvent modulation of the morphology of homochiral gadolinium coordination polymers and its impact on circularly polarized luminescence

The morphology of Gd(NO 3 ) 3 / R -, S -AnempH 2 assemblies is controlled by solvent. The spiral bundles (R-,S-1) are CPL active with asymmetric factor 2.8 times larger than that of crystals (R-,S-2), while spindle-shaped particles (R-,S-3) are CPL inactive.
