Ag (I)-based 2D metal frameworks with helical structures decorated by the homochiral camphor-10-sulfonic acid

Two two-dimension homochiral Ag (I) metal frameworks constructed from enantiopure camphor-10-sulfonic acid and hexamethylenetetramine have been synthesized at the room temperature. These two complexes with (6, 3) topology decorated by the homochiral camphor-10-sulfonic acid possess the unique helical structures. The result of Circular Dichroism (CD) spectroscopy confirms that the bulk materials are homochiral and also indicates the handedness of the single crystals can be controlled by the chirality of the camphor-10-sulfonic acid.
