The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In an article, author is Chahal, Mandeep K., once mentioned the application of 3491-12-1, Name is 4-[4-(4-aminophenoxy)phenoxy]aniline. Now introduce a scientific discovery about this category, Computed Properties of https://www.ambeed.com/products/3491-12-1.html.
Two new receptors viz. 2-bromoacetamido-5,7-dimethyl-1,8-naphthyridine (1a) and 2-chloroacetamido-5,7-dimethyl-1,8-naphthyridine (1b) containing 1,8-naphthyridine as fluorophore unit have been designed and synthesised. These receptors exhibited very high selectivity for F- ions among the various anions tested such as H2PO4-, OAc-, Cl-, Br-, I-, HSO4-, PF6-, ClO4-, BF4- and NO3- owing to anion-induced deprotonation of the amide NH by F- ions. Among the various cations tested (Na+, Ag+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+, Pb2+ and Mn3+), 1a exhibited selective detection of Hg2+ ions by binding with N1 and N8 atoms of the naphthyridine moiety. Receptor 1a has been explored as a dual-ion detector for F- and Hg2+ ions in two contrasting modes (fluorescence ‘turn-on’ and ‘turn-off’) which is supported by spectroscopic and lifetime measurements. 1a exhibited lower detection limits for F- (0.4 ppm) and Hg2+ (2.4 ppm) ions. These receptors were recovered from anionic species of 1a formed after addition of F- ions by treating with protic solvents such as CH3OH. The mode of binding was also confirmed by spectroscopic and DFT studies. The chemical inputs of F- and Hg2+ ions generate an output which satisfies the condition of two-input INHIBIT logic operators.
The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states.
