Study on solid-state circular dichroism spectroscopy and its application to chiral M(II) Schiff base complexes

摘要

An account on the application of solid-state CD on chiral metal complexes is briefly reviewed. Special focus is on the methods to record solid-state CD spectra of chiral solid sample, and then we switch to the comparison between solid-state and solution CD spectra of four pairs of chiral M(II) (M = Ni, Cu) Schiff base complexes. The solid-state CD spectra reveal that the chiral complexes maintain the same handeness found in solution states. But it is notable that there are some differences between the solid-state and solution CD spectra for the selective chiral complexes, which may be ascribed to some subtle tetrahedral distortion or conformational distinctions of the complexes between the two states.
