terminal groups, were synthesized as candidate gemini guests for the complexation of p-sulfonatocalix[4]arenes (SC4A). The 12 gemini guests are divided into five species according to the different terminal groups: imidazolium (G1–G3), pyridinium (G4–G6), quinolinium (G7), viologen (G8–G11), and 1,4-diazabicyclo[2.2.2]octane (DBO, G12). Their bindingstructures and stoichiometries with SC4A were examined by

towards Fe3+ in aqueous solution (H2O/CH3CN = 49:1, v/v) and H2PO4− in acetonitrilesolution with notable color change under UV light, evident changes were also noticed in fluorescence spectra. In fluorescence emission, the obvious turn-off was induced by Fe3+ in aqueous solution and the obvious turn-on as well as bathochromic-shift was induced by H2PO4− in acetonitrilesolution.
在这项工作中,我们报告了一系列基于a啶与咪唑鎓通过醚键结合的环烷荧光传感器。X射线晶体结构证明了在氢键和π-π相互作用的驱动下,这些环烷在固态下的自组装行为。传感器显示出朝向铁优异的选择性3+水溶液(H 2 O / CH 3 CN = 49:1,V / V)和H 2 PO 4 -乙腈与在UV光下显着的颜色变化的解决方案,明显变化也注意到在荧光光谱中。在荧光发射中,水溶液中的Fe 3+引起明显的熄灭,而H引起明显的点亮和红移。2 PO 4 -的乙腈溶液。
