Abstract

Dynamic M/P invertible helicity was successfully induced at a SiO₂ surface immobilized with a dynamic helical trinuclear cobalt complex, [LCo₃(NHMe₂)₆](OTf)₃, using chiral ((R) or (S))-1-phenylethylamine. Solid-state CD spectra and theoretical calculations suggested that the fixation of the M/P helical complex on the surface via coordination interactions was the key factor of the induced chirality at the surface.
