A dimeric complex of trivalent europium [Eu2Cl4(bc)2(ptpy)2] (1), containing the separate ligands 4'‐phenyl‐2,2':6',2''‐terpyridine (ptpy) and benzoate (bc) and a one‐dimensional double strand coordination polymer of the composition 1[EuCl2(cptpy)] (2) with 4‐[2,2':6',2''‐terpyridin]‐4'‐yl‐benzoate (cptpy) were obtained. The products exhibit structural similarities despite the character of joint and separate functionality of the ligands. The dimer 1 shows photoluminescence with high quantum yield [61(2) %]. Eu3+ emission lifetime is 1.493(1) ms at room temperature and rises to 1.649(1) ms upon cooling to 77 K.

Joint(III)与联合和分开的特吡啶和苯甲酸酯的配位聚合物和二聚配合物的相似性

三价euro [Eu 2 Cl 4(bc)2(ptpy)2 ](1)的二聚体复合物,包含单独的配体4'-苯基-2,2':6',2''-吡啶(ptpy)和苯甲酸甲酯(BC - )和组合物的一维双链配位聚合物1 [的EuCl 2(cptpy)](2)使用4- [2,2 ':6',2 '' -三联吡啶] -4'获得了苯甲酸基酯(cptpy )。尽管配体具有联合和分开的功能,但产品仍显示出结构相似性。二聚体1显示出具有高量子产率[61(2)%]的光致发光。欧盟3+ 室温下的发射寿命为1.493(1)毫秒,冷却至77 K时的发射寿命为1.649(1)毫秒。
