    reactions we have synthesised a series of star- and banana-shaped oligomers with a pyrimidine unit as the central core and π-conjugated arms consisting of aromatics bearing electron-donor substituents. The position of the arms as well as the nature of their substituents were investigated with a view to accessing compounds that exhibit interesting light-emitting properties. The best fluorescence quantum yields
    通过使用 Suzuki-Miyaura 交叉偶联反应,我们合成了一系列星形和香蕉形低聚物,以嘧啶单元为中心核,π 共轭臂由带有电子给体取代基的芳烃组成。研究了臂的位置及其取代基的性质,以期获得具有有趣发光特性的化合物。用对-(二甲氨基)苯基或2-呋喃基取代的香蕉形嘧啶获得最佳荧光量子产率。以苯、嘧啶或s-三嗪为中心单元的低聚物的光学性质的比较表明,嘧啶化合物给出了最好的结果。一些合成的低聚物表现出溶剂化变色特性和 pH 敏感性,

    Biarylpyrimidines bearing ω-aminoalkyl substituents have been designed as ligands for high-order DNA structures: spectrophotometric, thermal and competition equilibrium dialysis assays showed that changing the functional group for substituent attachment from thioether to amide switches the structural binding preference from triplex to tetraplex DNA; the novel ligands are non-toxic and moderate inhibitors of human telomerase.

    highest-energy emitter is the cyanide derivative whilst the lowest is the complex with the dithienylpyrimidine. The trends in both the absorption and emission energies as a function of ligand substituent have been rationalised accurately with the aid of TD-DFT calculations. The lowest-excited singlet and triplet levels correlate with the trend in the HOMO–LUMO gap. All the complexes have quantum yields that are
    已经制备了八种双核铱(III)配合物的新家族,其特征在于4,6-二芳基嘧啶L y为双-N-C-配位桥联配体。金属离子还通过基于1,3-二(2-吡啶基)苯的末端N,C,N-环金属化配体L X,以及通过单齿氯化物或氰化物来配位。化合物的通式为Ir L X Z } 2 L y(Z= Cl或CN)。该家族包括具有三个不同的L X配体和五个不同的二芳基嘧啶L y的实例,其中四个是二苯基嘧啶,一个是二噻吩基嘧啶。必需的配体已经通过标准的交叉偶联方法合成。配合物的合成涉及两个步骤,其中L X H与IrCl 3 ·3H 2 O反应形成[Ir L X Cl(μ-Cl)] 2形式的双核配合物,然后用二芳基嘧啶L y H 2。至关重要的是,每个复合物仅以单一化合物形式形成:强反式金属化环的影响决定了配体的相对位置,而对称取代的三齿配体的使用消除了当双双齿单元通过桥连的配体连接时获得的Λ和Δ对映体的可能性。该族
