Chiral Kagome Network from Thiacalix[4]arene Tetrasulfonate at the Interface of Aqueous Solution/Au(111) Surface: An in Situ Electrochemical Scanning Tunneling Microscopy Study

A chiral Kagome network was fabricated at an aqueous solution/Au(111) interface by using a complicated stereo supramolecule thiacalix[4]arene tetrasulfonate as a building block. It opens the possibility to construct a 2D nanoporous network by various functional supramolecules and shows potential application in host-guest chemistry as well as chiral resolution.
