A series of CdII/ZnII coordination polymers containing helical chains constructed from a “V”-like bis-pyridyl-bis-amide and various dicarboxylates: Assembly, structures, photoluminescent and selective photocatalysis

Eight CdII/ZnII 2D coordination polymers constructed from an unprecedented semi-rigid bis-pyridyl-bis-amide and various dicarboxylates have been prepared and charaterized. The semi-rigid “V”-like bis-pyridyl-bis-amide plays an important role in constructing 1D helical subunit.
