A sensor including a fluorinated receptor can be used to identify an analyte through shift in
19
F NMR resonance of the receptor when the receptor interacts with the analyte.
Novel ruthenium sensitizers with a dianionic tridentate ligand for dye-sensitized solar cells: the relationship between the solar cell performances and the electron-withdrawing ability of substituents on the ligand
novel rutheniumsensitizers (TUS sensitizers) with a dianionic tridentate ligand (pyridine-2,6-dicarboxyamidato and its derivatives) have been synthesized for application to dye-sensitized solarcells (DSCs). These TUS sensitizershave much larger molar absorption coefficients in the wavelength range below 600 nm compared with those of Black dye which is a structural analog and a highly efficient ruthenium

A chemosensory system is reported that operates without the need for separation techniques and is capable of identifying anions and structurally similar bioactive molecules. In this strategy, the coordination of analytes to a metal complex with an open binding cleft generates “static structures” on the NMR timescale. Unique signals are created by strategically placing fluorine atoms in close proximity
据报道,化学感应系统无需分离技术即可运行,并且能够识别阴离子和结构相似的生物活性分子。在该策略中,分析物与具有开放结合裂缝的金属络合物的配位在 NMR 时间尺度上产生“静态结构”。通过策略性地将氟原子放置在靠近结合分析物的位置来产生独特的信号,这样微小的结构差异就会引起不同的19 F NMR 位移,从而可用于识别每种分析物。该方法的实用性通过量化咖啡中的咖啡因含量、通过识别茶和能量饮料中的成分以及通过区分距结合位点六个碳原子具有远程结构差异的多种生物胺来说明。我们进一步证明了复杂混合物中多种中性和阴离子物种的同时识别。
