Cholesterol-decorated porphyrin with circularly polarized luminescence: Design, synthesis and properties

Binaphthalene-Assisted Axial Chirality in Porphyrins: Toward Solid-State Circularly Polarized Luminescence from Self-Assembled Nanostructures

“…A porphyrin dimer possessing axial chirality was synthesized by Sugiura and co-workers . For the limited literature available on the excited-state chiral investigations of porphyrins, the CPL signals were found to be extremely weak. − In this context, molecular self-assembly could be thought of as an effective approach to fabricate nanostructures that can emit chiral light. , Due to their favorable structural features, porphyrins are well-known to form supramolecular architectures through strong hydrogen bonding and π–π stacking interactions, − and this can be a viable alternative for achieving enhanced CPL activity. In this regard, there has been no effort toward designing simple enantiomeric pairs of porphyrin nanostructures that exhibit clear CPL signals.…”
