Keywords: lead mandelate methylbipyridine coordination polymer preparation thermal stability homochirality; fluorescence crystal structure lead mandelate methylbipyridine coordination polymer.They researched the compound: 5,5′-Dimethyl-2,2′-bipyridine( cas:1762-34-1 ).Recommanded Product: 1762-34-1. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1762-34-1) here.
Three new Pb(II) coordination polymers, namely [Pb2(mand)2]n (1), {[Pb(L-Hmand)(NO3)(5,5′-DM-2,2′-bipy)]·2H2O}n (2-L), {[Pb(D-Hmand)(NO3)(5,5′-DM-2,2′-bipy)]·2H2O}n (2-D) (H2mand = D/L-mandelic acid, 5,5′-DM-2,2′-bipy = 5,5′-dimethyl-2,2′-bipyridyl), have been prepared Their structures have been determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses, powder X-ray diffraction and thermogravimetric analyses. Complex 1 crystallizes in the triclinic system with space group P-1, and displays a 2D layer structure. Complexes 2-L and 2-D are pairs of enantiomers. They crystallize in the same chiral space group P212121 and feature a 1D chain structure. The influence of the temperature and steric-hindrance of 5,5′-dimethyl-2,2′-dipyridyl mols. on constructing enantiomeric Pb(II) coordination polymers based on chiral mandelic acid ligands have been demonstrated. In addition, the CD (CD) spectroscopy of 2-L and 2-D exhibit obvious pos. or neg. Cotton effects indicating their homochirality. The luminescent properties of 1, 2-L and 2-D in the solid state have also been investigated.
There is still a lot of research devoted to this compound(SMILES：CC1=CN=C(C=C1)C1=NC=C(C)C=C1)Recommanded Product: 1762-34-1, and with the development of science, more effects of this compound(1762-34-1) can be discovered.
