Triazole-amide isosteric pyridine-based supramolecular gelators in metal ion and biothiol sensing with excellent performance in adsorption of heavy metal ions and picric acid from water

Pyridine-based small molecular gelators 1-4, having a triazole-amide isosteric relationship, have been synthesized. Compounds 1-3 exhibit excellent gelation from DMSO-H2O (1?:?2, v/v), while compound 4 forms a gel in the presence of Ag+ ions in DMSO-H2O (1?:?2, v/v). The change from triazole to isosteric amide has a marked effect on the gelling abilities, minimum gelation concentrations (mgc), thermal stability, mechanical properties, metal ion-responsive character and adsorption properties of the structures, as established by various techniques. All the gels have been successfully applied in sophisticated sensing kits for the selective detection of Cu2+ and Ag+ ions and thiol-containing amino acids. The triazole-based gelators 1 and 3 adsorb heavy metal ions from water with greater efficiency than the isosteric amide-based gelators. The metallogel 4-Ag+ can be used in the efficient removal of picric acid (a nitro explosive) from water.

Synthesis and characterisation of novel 1,3-bis{(6-aryl-1,2,4-triazolo [3,4-b][1,3,4]thiadiazol-3-yl)-methoxy}benzenes under microwave irradiation

Eleven novel 1,3-bis{(6-aryl-1,2,4-triazolo[3,4-b][1,3,4]thiadiazol-3-yl)- methoxy}benzenes have been synthesised in high yields by the condensation of 5,5'-[1,3-phenylene-bis(oxymethylene)]bis(4-amino-3-mercapto-1,2,4-triazole) with substituted benzoic acids in the presence of phosphorus oxychloride under microwave irradiation. Compared with the conventional heating method, this method is facile, rapid and efficient. The structures of all new compounds were characterised by 1H NMR, IR, MS and elemental analysis.

Enhanced Basicity of the 2-Position of 1,3-Dialkoxybenzenes in S1: Acid Catalyzed Photochemical Proton/Deuteron Exchange

The photochemistry of several 1,3-dialkoxy-substituted benzenes 1-8 has been studied in aqueous H2SO4 (D2SO4) solution.In contrast to ground state behaviour, all of these compounds (with the exception of 7) are photoprotonated efficiently (via S1) and almost exclusively at the 2-position (and to a much lesser extent at the 5-position) to give dialkoxy-substituted cyclohexadienyl cation intermediates (2,6-dialkoxybenzenonium ions), resulting in proton/deuteron exchange of the 2-position of the benzene ring for all systems except 4 (and 7).In the ground state, protonation takes place predominantly at the 4-position for 1-4 and at the 6-position for 5 and 6.In the case of 4, photoprotonation at the 2-position is implicated by observation of fluorescence quenching by acid but deuterium exchange at this position is not possible.Photoprotonation (quenching) rate constants (kH) were calculated by Stern-Volmer analysis of steady state fluorescence quenching by proton and are in the range 0.9-3E9 M-1 s-1.Quantum yields for deuterium incorporation in 4:1 aqueous D2SO4-CH3CN are reported for several substrates at selected acidities.The sigmoid dependence of plots of fluorescence quenching vs acidity is used to give estimated pKBH(1+)* of ca. 0.1-0.5 for these substrates, indicating that they are much more basic in S1 than in S0.

Enhanced basicity of 1,3-dialkoxy-substituted benzenes: cyclophane derivatives

The photoprotonation of four dialkoxy-substituted benzenes in their excited singlet states has been studied.The parent systems 4 and 5 are regioselectively photoprotonated at the 2-position, with significant quantum efficiencies for deuterium incorporation at acidities greater than pH 2.The structurally related cyclophane derivatives 6 anf 7 did not show any deuterium exchange over the same acidity range but fluorescence quenching by proton (in aqueous solution) and laser flash photolysis structural constraints imposed by the most stable conformation adopted by these m olecules (6 and 7), the attacking proton (deuteron) is also the proton (deuteron) that is deprotonated from the cyclohexadienyl cation (2,6-dialkoxybenzenonium ion) intermediate, resulting in the absence of incorporation of deuterium.
