Chirality induction to achiral molecules by silica-coated chiral molecular assemblies

Abstract

Hybrid silica-organic nanohelices are used to organize a large variety of nonchiral small organic molecules or inorganic anions to nanometer-sized assemblies. Such chiral organization of achiral molecules induces chiroptical properties as detected by vibrational or electronic circular dichroism (CD), as well as from circularly polarized luminescence (CPL).

Keywords: circular dichroism; circularly polarized luminescence; excimer emission; induced chirality; silica nanohelice.
