Design of a zinc(II) ion specific fluorescence sensor
摘要:
We report the synthesis of {[3-(biscarboxymethylaimino)-2-methoxy-5-methylphenyl]carboxymethylamino}acetic acid, which functions as a Zn2+ selective fluorescence probe (sensor). (c) 2006 Elsevier Ltd. All rights reserved.
Diamino polyacetate benzene compounds are used as a selective fluorescence probe, sensor, or binders for divalent metal ions. The compounds provide for uses as divalent metal ion sensors in diagnostic applications and binders for environmental and medical treatments.

foldamer-based approach to modulating the thermal and mechanical properties of cross-linked n-butyl methacrylate copolymers. Intramolecularly hydrogen-bonding-induced folded aromatic amide segments were designed and prepared, which reacted with a salicylaldehyde-bearing prepolymer to form cross-linked copolymers. As a control, analogous aromatic cross-links incapable of forming discrete folded structures

Cyclicureaunits bound to anisyl or methylene units have been incorporated into 20-membered ring hosts whose complexation of alkali metal and ammonium ions show high binding free energies, high extraction rates, and high ion selectivities.
Disclosed are methods for making 1,3- and 1,4-diamino-phenyl intermediates by utilizing bis-amination of ortho-substituted aryl halides.

stacking structures were observed. The 1H (DOSY) NMR, UV−vis, and fluorescent experiments indicated that the new rigidified macrocyclescomplexfullerenes or coronene in chloroform through intermolecular π-stacking interaction. The association constants of the corresponding 1:1 complexes have been determined if the stacking was able to cause important fluorescent quenching of the macrocycles or coronene
