文摘

Two novel one-dimensional coordination polymers, single helicate [Zn(SPh)₂(TPyTA)(EG)]_n (EG=ethylene glycol) (1) and zig-zag structure [Zn(SPh)₂(BPyVB)]_n (2), were synthesized under solvothermal conditions at 150 ¡ãC or room temperature by the co-assembly of Zn(SPh)₂ and organic linkers such as 2,4,6-tri(4-pyridyl)-1,3,5-triazine (TPyTA) and 1,3-bis(trans-4-pyridylvinyl)benzene (BPyVB). X-ray crystallography study reveals that both polymers 1 and 2 crystallize in space group P2₁/c of the monoclinic system. The solid-state UV-vis absorption spectra show that 1 and 2 have maxium absorption onsets at 400 nm and 420 nm, respectively. TGA analysis indicates that 1 and 2 are stable up to 110 ¡ãC and 210 ¡ãC.
