Induced chirality at the surface: fixation of a dynamic M / P invertible helical Co 3 complex on SiO 2 .

Dynamic M / P invertible helicity was successfully induced at a SiO 2 surface immobilized with a dynamic helical trinuclear cobalt complex, [LCo 3 (NHMe 2 ) 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.
