New Types of Homochiral Helical Coordination Polymers Constructed by exo‐Bidentate Binaphthol Derivatives

Abstract Assembly of axially chiral ( S )‐2,2′‐bis(3‐pyridylmethyleneoxy)‐1,1′‐binaphthalene [( S )‐L 1 ] and ( S )‐2,2′‐bis(4‐pyridylmethyleneoxy)‐1,1′‐binaphthalene [( S )‐L 2 ] with AgNO 3 resulted in a double‐stranded helical coordination polymer encapsulating guest water molecules and a helix‐like complex with inter‐immersion clefts, respectively, in which helical chirality is due to axial chirality of the 1,1′‐bi‐2‐naphthol scaffold.
