  Four M(II)-coordination polymers (M=Zn(II) and Cd(II)) based on a flexible 1,2-bis(pyridin-3-yloxy)ethane ligand: Syntheses, structures and photoluminescent properties

  摘要：

  Four coordination polymers, namely {[Zn(L)(2)[(ClO4)(2))n (1), [Zn(L)(ipa)(n) (2), Cd(L)(chdc).2H(2)O](n) (3) and [Cd(L)(0.5)(pydc).0.5H(2)O](n) (4) (H(2)ipa = isophthalic acid, H2chdc = cyclohexane-1,4-dicarboxylic acid, H2pydc = pyridine-2,6-dicarboxylic acid), have been synthesized based on a flexible ligand 1,2-bis(pyridin-3-yloxy)ethane (L) under hydrothermal conditions. Their structures are determined by X-ray single-crystal analyses, IR spectra and X-ray powder diffractions (XRPD). In 1, the infinite 2D square sheets arrange regularly to form 1D channels containing ClO4- anions. 2 exhibits wave-like network, which is further extended into a 3D framework via interlayer C-H center dot center dot center dot X (X = pi, O) interactions. With different co-ligands, 3 shows a 2D structure, while 4 exhibits a intriguing 3D supramolecular framework. In 1-4, L adopts different conformations in the solid state. The various conformations of L, with the different co-ligands, play an important role in structural diversity. The thermogravimetric analyses and photoluminescent properties of them were also investigated. (C) 2013 Elsevier B.V. All rights reserved.

  摘要：

  摘要：合成并结构表征了两种光致发光的铜(I) 碘化物无机-有机杂化材料，分别为1D-Cu2I2(bpoe)2（1）和1D-Cu2I2(bbtpe-m)2（2）（bpoe = 1,2-双（吡啶-3-氧基）乙烷，bbtpe-m = 1,1'-(3-甲基戊烷-1,5-二基)双(1H-苯并[1,2,3]三唑)）。两种材料均为由Cu2I2菱形二聚体通过双齿配体连接而成的链状结构。它们的发射颜色从青色到黄色，固态下具有相对较高的内部量子产率。通过改变配体的LUMO能量，可以实现可调的带隙和发射颜色。这些结构稳定且坚固，可在高达260°C的温度下保持稳定，再加上它们高效可调的发光、简便的合成和无毒的特性，这些化合物展示了作为稀土元素（REE）无荧光粉的潜力。

  New atropisomeric bidentate bipyridine-based ligands (3,3′-(ethylenedioxy)-2,2′-bipyridine 3; 3,3′-(propylenedioxy)-2,2′-bipyridine 4; 3,3′-(butylenedioxy)-2,2′-bipyridine 5) containing a bridge between the 3,3′ positions of the aromatic rings have been prepared. Together with the previously reported analogous ligands ((R)-3,3′-(1-methylethylenedioxy)-2,2′-bipyridine) 1 and ((S,S)-3,3′-(1,2-dimethylethylenedioxy)-2,2′-bipyridine) 2, they were used to synthesize the corresponding bis-chelated dicationic complexes [Pd(N–N)2][PF6]2. Crystal structures and comparison of the data obtained by X-ray analysis on four of these complexes is reported. These palladium compounds were used as precatalysts in the CO/styrene and CO/4-Me-styrene copolymerization reactions, where they showed that small variations in the ligand backbone remarkably affects the productivity of the catalytic system.

  新的双齿双吡啶类配体（3,3′-(乙烯醚基)-2,2′-双吡啶 3；3,3′-(丙烯醚基)-2,2′-双吡啶 4；3,3′-(丁烯醚基)-2,2′-双吡啶 5）已被合成，这些配体在芳香环的3,3′位之间有一个桥连接。结合之前报道的类似配体（(R)-3,3′-(1-甲基乙烯醚基)-2,2′-双吡啶）1 和 ((S,S)-3,3′-(1,2-二甲基乙烯醚基)-2,2′-双吡啶）2，它们被用于合成相应的双配位阳离子复合物 [Pd(N–N)2][PF6]2。报告了这四个复合物通过X射线分析获得的晶体结构和数据比较。这些钯化合物被用作CO/苯乙烯和CO/4-甲基苯乙烯共聚合反应的前催化剂，显示出配体骨架的小变化显著影响催化体系的产物产量。
