    Cooperative Binding in a Phosphine Oxide-Based Halogen Bonded Dimer Drives Supramolecular Oligomerization
    摘要:
    Triphenylphosphine oxide forms halogen-bonded (XB) complexes with penta-fluoroiodobenzene and a 1,4-diaryl-5-iodotriazole. The stability of these complexes is assessed computationally and by P-31 NMR spectroscopy in toluene-d, solution, where both complexes are weakly associated. This knowledge is applied to the design and synthesis of two self complementary phosphine oxide-iodotriazole hybrids that incorporate a phosphine oxide XB acceptor and a 1,4-diphenyl-5-iodotriazole XB donor within the same molecule. The self complementary design of these modules facilitates their assembly in both toluene-d(8) and, surprisingly, DCM-d(2) into dimers, with significant stabilities, through the formation of halogen bonded diads. The stability of these assemblies is a result of significant levels of cooperative binding that is present in both solvents. The connection of two of these hybrid units together, using a flexible spacer, facilitates the aggregation of these modules in DCM-d(2) solution, through halogen bonding, forming oligomeric assemblies.

  • Tagged phosphine reagents to assist reaction work-up by phase-switched scavenging using a modular flow reactor

    The use of three orthogonally tagged phosphine reagents to assist chemical work-up via phase-switch scavenging in conjunction with a modular flow reactor is described. These techniques (acidic, basic and Click chemistry) are used to prepare various amides and tri-substituted guanidines from in situ generated iminophosphoranes.

    electron‐withdrawing group conjugated to electron‐donating groups, such as amino or ether groups, with a conjugated rod consisting of arylene–vinylene or arylene–ethynylene building blocks—were prepared. These compounds were efficiently synthesized by a Grignard reaction followed by Sonogashira coupling. Their photophysical properties including absorption, emission, time‐resolved fluorescence, and two‐photon absorption
    一系列棒状和相关的三分支推挽式衍生物,含有氧化膦或化膦(PO或PS),作为吸电子基团,与供电子基团(例如基或醚基团)共轭准备了由亚芳基-亚乙烯基或亚芳基-亚乙炔基组成的杆。这些化合物通过格利雅(Grignard)反应然后Sonogashira偶联有效合成。研究了它们的光物理性质,包括吸收,发射,时间分辨的荧光和双光子吸收(TPA),并特别注意其结构与性质之间的关系。这些荧光团显示出很高的荧光量子产率,并且溶剂依赖性实验表明,激发后会发生有效的分子内电荷转移,从而导致高极性激发态,通过在端基和共轭接头上进行修饰,可以显着提高其极性。棒形和相关的三分支系统显示出相似的荧光特性,这与推挽分支之一上的激发定位一致。通过使用更强的电子供体或用亚芳基-亚乙烯基取代亚芳基-亚乙炔基连接基,会引起低能单光子吸收和TPA谱带的明显红移。有趣的是,可观察到TPA反应的显着增强,而OPA强度仅受到微弱的影响
