  clinical copper-related disease diagnosis. In this work, a near infrared (NIR) fluorescent probe, CySBH, with a salicylaldehyde benzoyl hydrazone group as a selective and sensitive receptor for Cu2+ was designed and synthesized. The specific coordination of the salicylaldehyde benzoyl hydrazone group in CySBH with Cu2+ can induce a distinct quench of the fluorescence intensity, allowing for real-time tracking

  开发高灵敏度和选择性检测生命系统中Cu 2+的方法对于临床铜相关疾病的诊断具有重要意义。在这项工作中，设计并合成了一种近红外（NIR）荧光探针CySBH，它具有水杨醛苯甲酰腙基团作为Cu 2+的选择性和敏感受体。CySBH中的水杨醛苯甲酰腙基团与Cu 2+的特异性配位可以引起荧光强度的明显猝灭，从而实现对Cu 2+的实时跟踪。我们已经证明 CySBH 可以快速识别 Cu 2+具有良好的选择性和高灵敏度。此外，在低细胞毒性的基础上，该探针用于通过荧光成像对两个细胞系中的Cu 2+进行可视化。此外，由于其近红外发射特性，CySBH 还可用于体内监测 Cu 2+ 。 这些总体结果表明，近红外荧光探针 CySBH 为生命系统中 Cu 2+的选择性和灵敏监测提供了一种新方法。

• Metal ions-triggered photo-induced fluorescence change in rhodamine B-based photo-responsive complexes

  Photo-responsive materials with tunable properties by multiple stimuli have been widely used as molecular machines, molecular logic gates, optical data storages, etc. In this work, we report a rhodamine B-based photoresponsive system, whose properties could be facilely modulated by metal ions (Zn(II). Ni(II) and Hg(II)). These metal ions endow the complexes (L-Zn, L-Ni and L-Hg) with similar photochromic property but distinctly different photo-induced fluorescence change. Upon UV light irradiation, the spirolactam ring in rhodamine B moiety turned from a close form to an open form, along with enlarged conjugated structure with intense absorbance. Interestingly, fluorescence "turn off", "no change" and "turn on" responses were induced by Zn(II), Ni(II) and Hg(II) respectively upon UV light irradiation. Taking advantage of the prominently different characteristics caused by metal ions, different logic gates were designed by simply varying the inputs of metal ions and UV light. This work provided a new strategy for developing multifunctional photo-responsive materials, which were further beneficial for constructing photo-controlled logic gates with tunable performance.

• Structural investigations of aroylhydrazones derived from nicotinic acid hydrazide in solid state and in solution

  Structural forms of aroylhydrazones derived from nicotinic acid hydrazide have been studied in the solid state by FT-IR spectroscopy and in solution by NMR, UV-Vis and ATR spectroscopy. The studied compounds were N'-benzylidene-3-pyridinecarbohydrazide (I), N'-(2,4-dihydroxyphenylmethylidene)-3-pyridine-carbohydrazide (2), N'-(5-chloro-2-hydroxyphenylmethylidene)-3-pyridinecarbohydrazide (3), and N'-(3,5-dichloro-2-hydroxymethoxyphenylmethylidene)-3-pyridinecarbohydrazide (4). The compound 1 adopted the most stable ketoamine form (form I,-CO-NH-N=C-) in the solid state as well as in various organic solvents. In mixtures of organic solvents with water the UV-Vis and ATR spectra implied intermolecular hydrogen bonding of 1 with water molecules. The presence of both tautomeric forms land II (form II, -COH=N-N=C-) was proposed for the solid substance and highly concentrated solutions of 2, whereas form I was detected as the predominant one in diluted solutions. For compounds 3 and 4a coexistence of forms land III (form III,-CO-NH-NH-C=C-CO-) was noticed in the solid state and in polar protic organic solvents. The conversion to form III was induced by increasing the water content in the solvent mixtures. This process was the most pronounced for compound 4. When exposed to daylight, an appearance of a new band was observed during time in the UV-Vis spectrum of 4 in organic solvent/water 1/1 mixtures, which implied that tautomeric interconversion was most likely followed by E/Z isomerisation.
