  The effect of polyether terminal chains in the liquid crystalline behavior of ortho-palladated complexes

  摘要：

  A series of benzylideneanilines bearing terminal polyether chains, HL (HL=R-C6H4-CH=N-C6H4-R': R=OC8H17, R'=O(CH2CH2O)(2)C2H5; R=O(CH2CH2O)(2)C2H5, R'=OC8H17; R=R'=O(CH2CH2O)(2)C2H5: R=OC12H25, R'= O(CH2CH2O)(3)C2H5; R=O(CH2CH2O)(3)C2H5, R' = OC12H25; R = R' = O(CH2CH2O)(3)C2H5) have been prepared. Their dinuclear. [Pd(mu-X)L](2) (X = OAc, Cl, Br, SC8), [Pd-2(mu-SCn)(mu-X)L-2] (X = OAc, Cl; n = 8, 2) and mononuclear orthopalladated derivatives. Pd(acac)L, Pd(Ala)L, are reported and their mesogenic properties are compared with those of the analogous compounds with alkoxy chains. In general a great lowering in the melting points is produced for all the products. The free ligands and the alanine complexes are not liquid crystals. The chloro-bridged complexes bearing alkoxy and short polyether chains (O(CH2CH2O)(2)C2H5) Show the larger improvement of mesogenic properties. Longer polyether chains (O(CH2CH2O)C2H5) result usually in a destabilization of the mesophases. If only polyether chains are present, the destabilization is important regardless of the chain length. The ability of these molecules as ionic extractants and transporters was qualitatively evaluated for the more propitious cis-dinuclear complexes. which in fact showed some extracting ability, modest but improved compared to the free ligands.

  Borondipyrromethene (Bodipy) dyes with strong solid-state photoluminescence are highly desirable for their applications in OLEDs. In this work, a series of meso-(4-R–C6H4)-substituted Bodipy dyes (R = H for B1; R = (OCH2CH2)nOCH2CH3, n = 0–3 for B2–B5, respectively) were prepared through an acid-catalyzed reaction. The flexible ether groups attached to the periphery of B2–B5 are expected to influence

  具有强固态光致发光的硼二吡咯亚甲基（Bodipy）染料对于其在OLED中的应用是非常需要的。在这项工作中，一系列内消旋-（4-R–C 6 H 4）取代的Bodipy染料（B1的R = H ； R =（OCH 2 CH 2）n OCH 2 CH 3，n = 0–3 B2-B5分别）是通过酸催化反应制备的。预计连接在B2-B5外围的柔性醚基会影响固态的分子排列和分子间的相互作用。B1-B4的晶体学分析揭示了内消旋-苯环几乎与茚并平面正交。在B1中观察到分子间π–π相互作用，但在B2–B4中不存在。因此，染料B1在固态时微弱发射，而B2-B4在红色区域中发射强，发射量子产率高达0.33。掺有B2的PMMA膜示两个分离的发射峰，并且它们的相对强度取决于浓度，随着浓度从5 wt％逐渐增加到80 wt％，导致荧光颜色从绿黄色变为红色。发现在基态下形成二聚体是造成在凝聚态下红色发射的原因。有效的OLED

• Novel Resorcin[4]arenes as Potassium-Selective Ion-Channel and Transporter Mimics
  作者：Angela J. Wright、Susan E. Matthews、Wolfgang B. Fischer、Paul D. Beer

  DOI：10.1002/1521-3765(20010817)7:16<3474::aid-chem3474>3.0.co;2-6

  A series of novel resorcin[4]arenes with extended it systems have been synthesised and developed as potassium-selective transporters. Resorcin[4]arenes that feature crown ether moieties function as efficient carriers of K+ across bulk liquid membranes showing enhanced selectivity over the other alkali metal ions relative to a model system (benzo[15]crown-5). Incorporation of functionalities suitable for pore formation, in addition to an extra annulus of aromatic residues, gives molecules which have remarkable ion-channel-mimicking behaviour in a biological lipid bilayer with outstanding K+/Na+ selectivity.
