Abstract

Two new zinc coordination polymers, {[Zn(iPrIPA)(bpa)]⋅2H₂O}_n (1) and [Zn₂(iPrIPA)₂(bpp)]_n (2) (iPrIPA = 5-i-propoxyisophthalate, bpa = 1,2-bis(4-pyridyl) ethane, bpp = 1,3-bis(4-pyridyl)propane), have been synthesized under hydrothermal conditions. Complexes 1 and 2 represent 3-D polythreaded supra molecular architecture consisting of corrugated 2D layer for complexes 1 and a 2D network consisting of alternating Zn1 binuclear and paddel-wheel Zn2 binuclear units for compound 2. The structural comparison of these two complexes demonstrates that the characteristics of auxiliary ligands play a key role in governing the coordination motifs and the final supramolecular lattices. Fluorescence emission and room temperature phosphorescence (RTP) behavior of 1 and 2 were also investigated.

两种新的锌配位聚合物{[Zn（iPrIPA）（bpa）] 2H ₂ O} _n（1）和[Zn ₂（iPrIPA）₂（bpp）] _n（2）（iPrIPA = 5-i-丙氧基间苯二酸酯，在水热条件下已经合成了bpa = 1,2-双（4-吡啶基）乙烷，bpp = 1,3-双（4-吡啶基）丙烷）。配合物1和2代表3-D多线程超分子结构，其中包括配合物1的波纹状2D层和由化合物2的交替的Zn1双核和桨轮式Zn2双核单元组成的2D网络。。这两种复合物的结构比较表明，辅助配体的特性在控制配位基序和最终的超分子晶格中起着关键作用。还研究了1和2的荧光发射和室温磷光（RTP）行为。
