  氢键硫醇经历非常规激发态分子内质子转移反应

  摘要：

  最近开设了有关硫醇相关氢键（H-bond）及其激发态分子内质子转移（ESIPT）反应的章节，其中化合物4'-二乙氨基-3-巯基黄酮（ 3NTF ）在环己烷溶液和固体，产生 710 nm 互变异构体发射，斯托克斯位移异常大，为 12,230 cm –1 。考虑到硫醇氢键与传统的鲍林型-OH或-NH氢键相比是非常规的，因此有必要及时探讨其与ESIPT之间的根本区别。然而，由于互变异构最低激发态的主导n π* 特征，硫醇相关的 ESIPT 往往是非发射性的。在此，基于3-巯基黄酮支架和π-延伸概念，设计并合成了一系列具有不同氢键强度和690-720 nm互变异构体的新系列4′-取代-7-二乙氨基-3-巯基黄酮NTF 。在环己烷中紫外 (UV) 激发时的发射。实验确定它们的氢键强度顺序为N-NTF < O-NTF < H-NTF < F-NTF ，而通过荧光上转换测量的 -SH ESIPT 速率为F-NTF

  Effect of phenyl ring substitution on J-aggregate formation ability of novel bisazomethine dyes in vapour-deposited films

  摘要：

  Bisazomethine dyes, which are synthesized using diaminomaleonitrile and aminobenzaldehydes, exhibit red fluorescence in solution and in the solid state. Several bisazomethine dyes are known to form J-aggregates in vapour-deposited films. In this work, novel bisazomethine dyes were synthesized and the effect of phenyl ring substitution on the J-aggregate formation in vapour-deposited films was examined. The optical properties of the dyes were examined in solution and in the solid state through molecular orbital calculations. Four derivatives were found to form J-aggregates in vapour-deposited films as determined from the shape of the spectrum and the absorption edge. (C) 2010 Elsevier Ltd. All rights reserved.

  Quinoline based fluorescent probes QNOH-MO and QNOH-OME were synthesized, and their photo-physical properties were carefully investigated. The probes were well characterized by 1H-NMR, 13C-NMR, ESI-MS, and single-crystal X-ray structure analysis. QNOH-MO and QNOH-OME can identify small changes in pH by colorimetric and fluorescence methods. In low pH range, these probes display a red fluorescence in

  合成了基于喹啉的荧光探针QNOH-MO和QNOH-OME，并对其光物理性质进行了仔细研究。通过1 H-NMR，13 C-NMR，ESI-MS和单晶X射线结构分析对探针进行了很好的表征。QNOH-MO和QNOH-OME可以通过比色法和荧光法鉴定pH的微小变化。在低pH范围内，这些探针在活细胞和固定细胞中均显示红色荧光。但是，随着pH值的增加，观察到的红色荧光减少，绿色荧光同时增加。理论计算和1很好地支持了pH依赖的从红色荧光到绿色荧光的转换。1 H NMR滴定实验。此外，还详细研究了这些探针在活细胞中成像pH变化的能力。此外，QNOH-OME已成功用于胆固醇分子的荧光标记，胆固醇分子是生物膜的重要组成部分，并用于脂质体制剂中，用于药物输送。另外，QNOH-MO被季铵化以诱导分子的固有阳离子性质。阳离子探针QNOH-MO-CA表现出改善的水溶性和pH感测效率。

  the cross-coupling reactions with aryl ethers via C-O bond activation have attracted broad interest. However, the functionalizations of C-O bonds are mainly limited to nickel catalysis, and selectivity has long been a prominent challenge when several C-O bonds are present in the one molecule. We report here the first chromium-catalyzed selective cross-coupling reactions of aryl ethers with Grignard reagents
