Chiral inversion of macroscopic helical structures in coordination polymers induced by lanthanide ions
Abstract
). Interestingly, the helicity of heavy lanthanide compounds R-1h-Ln (Ln = Gd-Ho) was also influenced by the M : L ratio and the autoclave filling degree. Thus, by adjusting these two parameters, R-1h-Ln (Ln = Gd, Tb, Dy) superhelices with identical compositions and structures but opposite helicity can be obtained. Further studies indicated that the compounds R-1h-Tb(M) and R-1h-Tb(P), possessing opposite helical orientations, exhibited circularly polarized luminescence (CPL) properties. Although their signals are weak, they are nearly mirror images of each other, indicating that the macroscopic helicity significantly affects their chiroptical properties.
