Research Abstract |
Many solid-state organic fluorophores composed of a single organic molecule have been reported. However, most of the previously reported organic fluorophores do not have chirality, and therefore, they do not show solid-state circularly polarized luminescence(CPL). In this study, chiral two-component supramolecular organic fluorophore was successfully prepared by using achiral fluorescent carboxylic acid molecule and chiral amine molecule. Intersetingly, it was found that the solid-state chiral optical properties of acid/amine supramolecular organic fluorophore can be controlled by changing the type of the achiral acid component molecule(that is, by changing the packing structure of the fluorescent unit) instead of changing the chirality of the chiral amine component molecule. Supramolecular organic fluorophores offering these functionalities are expected to be useful in the development of novel solid-state chiral supramolecular fluorophores.
