  Well-Defined Alternating Copolymers of Oligo(phenylenevinylene)s and Flexible Chains

  摘要：

  A series of alternating copolymers containing oligomeric bis(2-ethylhexyl)-p-phenylenevinylene (BEH-PPV) chromophores and conformational-flexible n-decyl or tetraethylene glycol chains were prepared. The polymerization was carried out using Sonogashira coupling conditions between monomers composed of an iodo-terminated PPV oligomer (trimer, pentamer, or septamer) and a bis(phenylacetylene)containing flexible chain. Polymers containing the n-decyl chain attained higher molecular weights compared to the tetraethylene glycol-containing polymers. 4-Ethynylanisole-capped oligomers (trimer, pentamer, or septamer) were prepared, and their solution photophysical properties were compared to the analogous polymeric materials. The solution optical properties of the polymers were primarily determined by chromophore length of the constituent oligomers. In contrast, the thin film fluorescence spectra of the polymers showed substantial differences between n-decyl and tetraethylene glycol containing materials, suggesting significant changes in the degree of interchain coupling in the solid state. The control of effective conjugation length afforded by these materials makes them a promising system for understanding electronic trap states in conjugated polymers.

  Five‐coordinated d6 metal complexes are relatively uncommon but can be useful building blocks for the construction of supramolecular assemblies. In this work we have used the strong trans effect of aryl and alkyl ligands for the synthesis of luminescent five‐coordinated organoiridium porphyrins, which are useful building blocks for the construction of metallamacrocycles and metallacages of iridium through metal–ligand

  五配位的d 6金属配合物相对不常见，但对于构​​建超分子组装体可能是有用的构建基块。在这项工作中，我们使用了芳基和烷基配体的强反式效应来合成发光的五配位有机铱卟啉，这是通过金属配位体在轴向上的金属-配体相互作用构建铱的金属链环和铱金属链的有用组成部分。铱卟啉（Ir（por））。使用不同的二或三位芳基或烷基接头作为轴向配体，在轴向位置配位Ir（por），以得到双核或三核五配位[Ir（ttp）} n（X）]（ttp = 5 ，10,15,20-四（对甲苯基）porphyrinato（2-）; n＝ 2，X ＝二芳基；n＝ 3，X ＝三烷基）。[Ir（ttp）} n（X）]可以在每个Ir（ttp）的另一个轴向位点与异位异氰酸酯或吡啶配体进一步配位，以产生空前的环状超分子金属卟啉组装体，包括四核和六核金属链环和六核金属环。Ir（por）金属lamcrocrocycles和金属漆在近红外区域显示
