Abstract

Crystalline and chiral supramolecular complexes can be self-assembled from linear polyethyleneimine and D- or L-tartaric acid. These complexes act as templates to direct nanofiber-based chiral silica, which showed remarkable chiraoptical properties and remained chiral even after sintering at ultrahigh temperatures. Achiral molecules and gold nanoparticles bound to the chiral silica became active in CD spectra owing to induced chirality.
