  From para-dimethoxybenzene toward crown benzenophanes: 1,3,10,14-tetraoxa[3.5]paracyclophane

  摘要：

  The title compound tetraoxa[3.5]paracyclophane (6) has been prepared and studied in order to investigate the evolution of spectroscopic properties in going from the monomer unit p-dimethoxybenzene (9) via the noncyclic bichromophoric reference compound 3b to 6. The X-ray structural analysis of 6 shows that the distance between the two aromatic carbon atoms linked to the smaller bridge is shorter than the van der Waals distance. The resulting electronic interaction is reflected by the perturbation of the UV spectrum of 6 (in particular by a distinct hypochromic effect) and in its charge-transfer complexes with TCNE and TCNQ, as compared to 9 and 3b. The fluorescence quantum yields show significant quenching as compared to 9. This process is related to the formation of a new, structureless red-shifted band with a maximum at 26 670 cm-1, comparable to that of the excimer of 9. From a Stern-Volmer plot the self-quenching rate constant of the latter, k(q) almost-equal-to 1.2 x 10(9) mol-1 s-1 is derived.

  of EM for a noncovalent intramolecular interaction. Introduction of rotors reduces the value of EM from this maximum in accord with a random walk analysis of the encounter probability of the chain ends (r−3/2). Noncovalent EMs never reach the very high values observed for covalent processes, which places limitations on the magnitudes of the effects that one is likely to achieve through the use of chelate

  合成了一个由四个双氨基甲酸酯（AA）和四个双酚（DD）组成的家族，并使用1表征了所有AA • DD组合之间的氢键相互作用在四氯化碳中的1 H NMR滴定。化学双突变体循环分析表明，在这些系统中没有次级静电相互作用或变构协同作用，因此该系统为研究化学结构与螯合协同作用之间的关系提供了理想的平台。测量了12种不同系统的有效摩尔浓度（EMs），其中连接两个H键位点的链中的转子数从5变为20。对于所有12种络合物，缔合常数的变化幅度均小于一个数量级， EM的变化非常小（0.1-0.9 M）。结果提供了EM和连接链中的转子数（r）之间的关系：EM≈10 r -3/2。10 M的值是非共价分子内相互作用的EM值的上限。根据对链条末端相遇概率（r -3/2）的随机游动分析，引入转子会从该最大值减小EM的值。非共价EM从未达到共价过程中观察到的很高的值，这限制了通过在超分子组装和催化中使用螯合剂的协同作用

  A bonded composite having excellent adhesiveness can be obtained by melt bonding a metallic material, preferably one having a surface treated with a triazinethiol compound, to a thermoplastic resin, preferably a thermotropic liquid-crystal resin, while incorporating at least one resin selected from the group consisting of oxygen-containing hydrocarbon resins, thermoplastic elastomers each containing structural units derived from an α,β-unsaturated carboxylic acid or its anhydride, polyamide resins, and non-liquid-crystal polyester resins as an agent for enhancing the effect of adhesion into the thermoplastic resin. When the thermotropic liquid-crystal resin has at least one constituent monomer selected from the group consisting of aromatic hydroxylamines, aromatic diamines, and aromatic aminocarboxylic acids, a high effect of adhesion to the metallic material can be obtained likewise. A composition comprising the thermotropic liquid- crystal resin, and a terpene resin or a thermoplastic polyester elastomer reduces the minimum charging pressure and eliminates problems concerning weld strength, appearance and others, thus being useful as an embedding material.
