Synthesis of Triphenylamine Molecules Having Multiple Hydrogen Bondings and Formation of Chiral Supramolecules |
| 초록 |
Organic compounds containing a TPA moiety can be assembled in chlorinated solvents under light irradiation. Light irradiation generates chlorine radicals that oxidize the TPAs into TPA cation radicals which induce stacking of the TPA molecules. However, it was found that the self-assembled structure didn`t have enough stability at high temperature and showed degradation of chirality as time goes on despite of the photo-polymerization. In this study, triphenylamine derivative having multiple hydrogen bonding sites (TPA-2a-SDA) was synthesized and self-assembled in chlorinated solvents. The chiral supramolecular polymers having improved stability was obtained by self-assembly induced by circularly polarized light (CPL). |
