چکیده
A new fluorescent chemosensor based on calix[4]arene bearing four iminoquinoline subunits on the upper rim was conveniently synthesized, which showed a remarkable enhanced fluorescent intensity in the presence of Cu(2+) ion and a high selectivity toward Cu(2+) ion over a wide range of tested metal ions in acetonitrile.

Amidofluorene-appended lower rim 1,3-diconjugate of calix[4]arene: synthesis, characterization and highly selective sensor for Cu2+
Functionalization of calix[4]arene with amidofluorene moieties at the lower rim led to formation of the 1,3-diconjugate of calix[4]arene L as a novel fluorescent chemosensor for Cu(2+). The receptor molecule L exhibited a pronounced selectivity towards Cu(2+) over other mono and divalent ions. The formation of the complex between L and Cu(2+) was evaluated by absorption, fluorescence and (1)H N...

متن کاملDevelopment of Conductometric Sensor Based on 25,27-Di-(5-thio-octyloxy)calix[4]arene-crown-6 for Determination of Ammonium
The conductometric sensor based on 25,27-di-(5-thio-octyloxy)calix[4]arene-crown-6 was developed for the quantitative analysis of ammonium. The calixarene was immobilized on the surface of the planar interdigitated electrodes by attachment of its dialkyl sulfide groups to the surface of the gold electrodes. The intrinsic ability of the calixarene to capture ammonium was studied in the conductom...
متن کاملAllosterically driven self-assemblies of interlocked calix[6]arene receptors.
The construction of self-assembled receptors based on flexible concave subunits is a challenging task and constitutes an interesting approach to mimic binding processes occurring in biological systems. The receptors studied herein are based on flexible calix[6]arene skeletons bearing three (or more) acid-base functionalities at their narrow rim. When complementary, they self-assemble in a tail-...
متن کاملLuminescence Properties of Self-Aggregating TbIII-DOTA-Functionalized Calix[4]arenes
Self-aggregating calix[4]arenes carrying four DOTA ligands on the upper rim for stable complexation of paramagnetic GdIII-ions have already been proposed as MRI probes. In this work, we investigate the luminescence properties of TbIII-DOTA-calix[4]arene-4OPr containing four propyl-groups and compare them with those of the analog substituted with a phthalimide chromophore (TbIII-DOTA-calix[4]are...
