  Solvent dependent colorimetric, ratiometric dual sensor for copper and fluoride ions: Real sample analysis, cytotoxicity and computational studies

  摘要：

  A novel colorimetric chemosensor based on terephthalic acid and pyridine aldehyde moiety was designed to detect Cu2+/F- ions in aqueous and DMSO solutions at physiological pH conditions with the detection limit of 0.25 mu M and 3 mu M for Cu2+/F- ions respectively. The probe was found to be highly selective to sense F- ion rather than CH3COO- and H2PO4- ions. Interestingly, the probe behaved as a promising receptor by detecting F- ions even in ordinary tap water through distinct colour change. Moreover, the chemosensor showed lower cytotoxicity against AGS cancer cells and thus found to be biologically friendly. The reversibility of probe-F- binding was investigated using HCl in UV-vis experiment. The binding mechanism of chemosensor to Cu2+/F- ions was elucidated based on the UV-vis spectroscopy, NMR, ESI-Mass spectroscopy and cyclic voltammogram techniques. Furthermore, theoretical investigation was carried out using Gaussian 09 program. (C) 2016 Elsevier B.V. All rights reserved.

• Cationic dinuclear Ir(III) complexes based on acylhydrazine ligands: Reversible piezochromic luminescence and AIE behaviours

  Ir(III) complexes containing same acylhydrazone ancillary ligands and easily tunable cyclometalated ligands have been rationally designed and synthesized. Both luminophores show excellent aggregation-induced emission (AIE) behaviours and high-contrast PCL properties. The powder X-ray diffraction (PXRD) studies suggest that the emission changes of complexes before and after grinding derive from effective transformation

  全面了解结构-特性相关性对于开发理想的压致变色发光（PCL）材料至关重要。牢记这一点，已经合理地设计和合成了两种新的阳离子双核金属Ir（III）配合物，它们含有相同的酰基hydr辅助配体和易调谐的环金属化配体。两种发光体均显示出出色的聚集诱导发射（AIE）行为和高对比度PCL特性。粉末X射线衍射（PXRD）研究表明，研磨前后配合物的发射变化源于结晶相和非晶相之间的有效转变。傅立叶变换红外光谱（FT-IR）进一步表明，配合物的PCL效应可归因于N–H与C之间的氢键紊乱O组。重要的是，将氢键位引入Ir（III）配合物中的原理为设计智能PCL材料提供了一种可行的方法。基于复杂的复合物1和2的PCL特性，分别成功地获得了有效的概念验证数据加密和可重写设备。
