摘要
用CoCl2·6H2O与萘-1,4-二羧酸（1,4-酰基）甲基和4,4'-（（吡啶-4-酰基）甲基）丙烷-1,3-二羰基}双（氧）二吡啶，[Co2(C12H6O4)2(C25H24N4O4)(H2O)2]n或[Co2(1,4-nda)2(PDP)(H2O)2]n,(1)，成功地合成了新型钴（II）配位聚合物[μ-4,4'-（（吡啶-4-酰基）甲基]丙烷-1,3-二羰基}双（氧）二吡啶（PDP））。化合物(1)具有由1,4-nda2-和PDP间隔剂复杂连接的坚固的三维框架。拓扑分析将该体系结构确定为一个点符号为{36·46·513·63}的（4,4）连接网络。紫外可见光谱在305nm处呈现出强烈的配体中心π→π*跃迁带。在532 nm （7 ns脉冲）下的z扫描测量显示出较强的反向饱和吸收活性，吸收系数为2.68 × 10-7 m W-1。该化合物有望在三阶非线性光学中应用。
Investigation into the third-order nonlinear optical properties of a three-dimensional cobalt(II) coordination polymer constructed from naphthalene-1,4-dicarboxylic acid and 4,4'-({2,2-bis[(pyridin-4-yloxy)methyl]propane-1,3-diyl}bis(oxy))dipyridine.
A novel cobalt(II) coordination polymer, poly[diaqua[μ-4,4'-({2,2-bis[(pyridin-4-yloxy)methyl]propane-1,3-diyl}bis(oxy))dipyridine]bis(μ-naphthalene-1,4-dicarboxylato)dicobalt(II)], [Co2(C12H6O4)2(C25H24N4O4)(H2O)2]n or [Co2(1,4-nda)2(PDP)(H2O)2]n, (1), has been successfully synthesized through the hydrothermal reaction of CoCl2·6H2O with naphthalene-1,4-dicarboxylic acid (1,4-ndaH2) and 4,4'-({2,2-bis[(pyridin-4-yloxy)methyl]propane-1,3-diyl}bis(oxy))dipyridine (PDP). Compound (1) features a robust three-dimensional framework intricately interconnected by 1,4-nda2- and PDP spacers. Topological analysis identifies this architecture as a (4,4)-connected net with point symbol {36·46·513·63}. The UV-Vis spectrum displays an intense ligand-centred π→π* transition band at 305 nm. Z-scan measurements at 532 nm (7 ns pulse) demonstrate strong reverse saturable absorption activity with an absorption coefficient of 2.68 × 10-7 m W-1. This compound is anticipated to be a promising candidate for applications in third-order nonlinear optics.
期刊介绍：
Acta Crystallographica Section C: Structural Chemistry is continuing its transition to a journal that publishes exciting science with structural content, in particular, important results relating to the chemical sciences. Section C is the journal of choice for the rapid publication of articles that highlight interesting research facilitated by the determination, calculation or analysis of structures of any type, other than macromolecular structures. Articles that emphasize the science and the outcomes that were enabled by the study are particularly welcomed. Authors are encouraged to include mainstream science in their papers, thereby producing manuscripts that are substantial scientific well-rounded contributions that appeal to a broad community of readers and increase the profile of the authors.
