Abstract

A right-handed helical motif is shown by the spiral silica shown in the picture. It is formed by sol-gel polycondensation of tetraethoxysilane in the gel phase supported by an azacrown-appended cholesterol gelator. This is rare example of 'chirality' being created in the inorganic material by the template method.
