Abstract

We demonstrate the direct induction of chirally arranged organic dye-linked polysilsesquioxane through a sol–gel transcription using a chiral supramolecular template. The chiral arrangement was confirmed by using electronic and vibrational circular dichroism and circularly polarized luminescence spectroscopies.
