A luminescent homochiral 3D Cd(II) framework with a threefold interpenetrating uniform net 8~6

摘要

A luminescent homochiral 3D metal-organic framework, [Cd(dtba)(bpp)]_(3n) (1) (H_2dtba = 2,2'-dithiobisbenzoic acid, bpp = 1,3-bis(4-pyridyl)propane), with an unprecedented threefold interpenetrating uniform network (8~6), constructed from [Cd(dtba)]_n single helices and [Cd(bpp)]_n double-stranded helices, has been synthesized via hydrothermal reaction. In recent years, homochiral metal-organic frameworks (MOFs) have attracted much attention because of their intriguing architectures and their potential applications in second-order nonlinear optical materials, chiral separation, asymmetric heterogeneous catalysts, ion exchange and so on.
