Preparation of chiral ladder-like polysilsesquioxanes and their chiral induction to anionic dye compound

Ladder-like polysilsesquioxanes containing chiral groups and ammonium chloride groups as side chains were prepared by the polymer reaction method. The chiralities of the resulting PSQs in methanol were induced to the anionic achiral porphyrin such as tetraphenylporphine tetrasulfonic acid (TPPS) while maintaining the monomeric state of TPPS, resulting in the observation of fluorescence emission due to TPPS.
