説明

Thiacalixarene (TCA), which is a macrocyclic host molecule, where benzene rings are combined with sulfur atom. TCA has unique capability such as making an inclusion compound in the cavity by non-covalent interactions such as hydrophobic, hydrogen bonding, π-π, and van der Waals interactions. Such an interaction between intra molecule or inter molecules are making beautiful 3D architecture, which is able to create intelligent molecular such as nanoscale capsules and cage structures. Those interactions play an important role in the living systems, frequently occur in supramolecular assemblies. These assemblies have great potential for selective guest encapsulation, drug delivery, transport, and catalysis in many applications, since the interior spaces can be functionalized to achieve different desirable functions. In an addition, TCA has affinity for the metal ion because of due to sulfur, which seems to be preferable for infinite intermolecular interaction in the solid state because their bridging sulfur moieties have a high affinity toward a wide range of metal ions，moreover in even the application field, metal extraction capability in especially for the platinum group metals (PGM) is so large.
