• Fluorescent Gelators for Detection of Explosives

  Carbazole-, quinoline-, benzothiazole-, and stilbene-containing fluorescent gelators are synthesized by connecting gelation-driving segments, and their gelation abilities are studied with 13 solvents. Fibrous thin-layer films are prepared on quartz plates from the solutions or gels, and they are studied as chemosensors for explosives. Fluorescence quenching of the films upon exposure to saturated TNT or RDX vapor is used to evaluate the abilities of the films to detect explosives. The relationship between the thickness of the thin-layer film and the quenching efficiency upon exposure to TNT is studied. The morphologies of the thin-layer films are observed by dynamic force mode scanning probe microscopy and discussed with regard to their fluorescence quenching. The interactions among chromophores in the gels, thin-layer films, and solutions are studied by variable-temperature spectroscopy. The mechanism of TNT detection is discussed from the viewpoint of the HOMO and LUMO energy levels.

  合成了含有氮杂环、喹啉、苯并噻唑和苯乙烯的荧光凝胶剂，通过连接促使凝胶化的片段，并使用13种溶剂研究它们的凝胶能力。在石英板上从溶液或凝胶中制备了纤维状薄膜，并将其作为化学传感器用于探测爆炸物。薄膜在接触饱和的TNT或RDX蒸气时的荧光淬灭被用来评估薄膜检测爆炸物的能力。研究了薄层膜厚度与接触TNT时淬灭效率之间的关系。通过动态力模式扫描探针显微镜观察薄层膜的形态，并讨论其与荧光淬灭的关系。通过可变温光谱学研究凝胶、薄层膜和溶液中色谱体之间的相互作用。从HOMO和LUMO能级的角度讨论了TNT检测机制。

  Two tridentate ligand systems bearing N-heterocyclic carbene (NHC), amine and carboxylate donor groups coupled to benzothiazole- or stilbene-based amyloid binding moieties were synthesised. Reaction of the imidazolium salt containing pro-ligands with Re(CO)5Cl yielded the corresponding rhenium metal complexes which were characterised by NMR, and X-ray crystallography. These ligands are of interest

  The imine ligand L1 was prepared by the reaction of 4-amino-4′-(dimethylamino)stilbene and 2-pyridinecarbaldehyde. The amine ligand L2 was obtained in good yield by the reduction of L1 with NaBH4. The complexes [ReX(CO)3(Ln)] (1a: X = Cl, n = 1; 1b: X = Br, n = 1; 2a: X = Cl, n = 2; 2b: X = Br, n = 2) were prepared through the reactions of equimolar solutions of the corresponding ligand and [ReX(CO)3(CH3CN)2]

  Urea-based molecular constructs are shown for the first time to be nonlinear optically (NLO) active in solution. We demonstrate self-assembly triggered large amplification and specific anion recognition driven attenuation of the NLO activity. This orthogonal modulation along with an excellent nonlinearity-transparency trade-off makes them attractive NLO probes for studies related to weak self-assembly and anion transportation by second harmonic microscopy.

  首次证明基于尿素的分子结构在溶液中具有非线性光学（NLO）活性。我们证明自组装触发了 NLO 活性的大幅扩增和特定阴离子识别驱动的衰减。这种正交调制以及出色的非线性-透明度权衡使它们成为有吸引力的非线性光学探针，用于通过二次谐波显微镜进行弱自组装和阴离子传输相关的研究。

  Kurtz powder test for second harmonic generation (SHG). The ferrocenyl derivatives have been found to exhibit SHG on irradiation at 1907 nm, whereas all of the derivatives containing NMe2 or OMe groups are SHG inactive. The crystal structure of [Mo(NO)HB(dmpz)3}ClOC6H4[CHCHC6H4(NMe2-4)]-4}] shows that, although the compound crystallises in a polar space group, the lattice contains pseudocentrosymmetrically
