Description

一种基于锌(Ⅱ)的五核金属有机配合物及其制备方法
技术领域
本发明涉及金属有机配合物领域,具体涉及一种基于锌(Ⅱ)的五核金属有机配合物及其制备方法。
背景技术
金属有机配合物是一种由金属离子与有机配体在一定条件下通过自组装合成的具有一维、二维或者三维结构的金属有机框架材料。金属有机配合物作为一种新型功能材料,具有孔隙率高、结构可塑、孔径大小均匀等特点。由于独特的多孔结构以及制备方法简便易行等特点,使其在荧光、磁性、吸附和载药等领域具有潜在的应用价值。
含有共扼电子效应的有机配体与含有d10电子构型的Zn2+和Cd2+等金属结合的金属有机配合物都可以发光,并且具有重复结构单元的金属有机配合物往往能够发出较强的荧光。金属有机配合物可通过改变金属配位来影响配合物的发光性能,在制备新型发光材料方面具有重要的应用价值。具有荧光特性的基于4,4'-氧联苯二甲酸和3,3'-二甲基-4,4'-联吡啶含氮有机配体的锌(Ⅱ)金属有机配合物的报道十分少见。

所述金属有机配合物的红外光谱数据(KBr)为:3449(vs),3151(s),1683(m),1605(vs),1559(m),1506(m),1398(vs),1307(m),1262(s),1159(s),1104(w),1080(w),1010(w),873(w),853(w),778(s),692(m),658(m),617(w),501(w),443(w),418(w)cm-1
所述金属有机配合物中,oba配体存在两种配位方式:一种桥连方式连接四个锌(II)离子,另一种桥连模式连接三个锌(II)离子;羟基氧原子(O6)连接三个锌(II)离子,而dmbpy配体也采用桥连方式连接两个锌(II)离子;基于上述连接方式,八个oba2-阴离子和两个桥连羟基氧配体连接5个锌(II)离子构筑成类似汉堡式的五聚体(Zn5O30N2)二级构筑单元,这些五聚体的二级构筑单通过dmbpy连接成一维链状结构,最后,这些一维链状结构被oba2-阴离子进一步连接成具有sxd拓扑结构的三维二重穿插网络结构;所述锌(Ⅱ)金属有机配合物在常温下为无色单晶,其重复结构单元中含有5个Zn2+阳离子,4个oba2-阴离子,一个dmbpy配体和2个羟基配体;Zn1和Zn2均为四配位的四面体几何构型,其中Zn1由三个不同的oba配体中的三个羧酸氧原子和一个侨联氧原子配位,而Zn2由两个不同的oba配体中的两个羧酸氧原子,一个dmbpy配体上的氮原子和一个桥连氧原子配位;Zn3由五个不同的oba配体上的五个羧酸氧原子和一个桥连氧原子配位形成六配位,为八面体几何构型。
本发明还提供了所述基于锌(Ⅱ)的五核金属有机配合物的制备方法,本发明所提供的制备方法采用本领域常用的水热反应法,将4,4'-氧联苯二甲酸和3,3'-二甲基-4,4'-联吡啶与Zn(NO3)2·6H2O混合后在水热反应条件下得到,具体包括以下步骤:
S1、将H2oba溶解分散在热水中,用NaOH溶液将pH调至7.0~8.0,得到配体溶液;
S2、在配体溶液中加入等摩尔量的Zn(NO3)2·6H2O和dmbpy,混合;然后将混合溶液加入到23mL聚四氟乙烯反应釜中,自生压力下保持130℃反应72h;
S3、将S2得到的产物过滤,收集晶体,并用无水乙醇洗涤后干燥,得到所述的基于锌(Ⅱ)的五核金属配合物。
