4,4′-联喹啉酸铅(Ⅱ)配位聚合物(英文)

Lead(Ⅱ) Coordination Polymer with 4,4'-biquinoline Ligand

消旋轴手性配体(R,S)-4,4′-联二喹啉-3,3′-二甲酸乙酯(DBD)(1)与Pb(OAc)2在吡啶催化水热140℃合成条件下合成一新颖的配位聚合物[Pb(BD)(pyridine)]n(3),荧光测量表明,该配位聚合物与有机配体一样,在390nm附近展现紫色荧光。

Hydrothermal treatment of racemic atropisomeric ligand diethyl（R,S）-4,4＇-biquinoline-3,3＇-dicarboxylate （DBD） （1） with Pb（OAc）2, in the presence of pyridine over 4 days at 140 ℃, offers the coordination polymer [Pb（BD） （pyridine）]n （3）, which displays purple luminescent spectrum at about 390 nm without much transfer comparing to that of the free ligand.
