A luminescent on-off probe based calix[4]arene linked through triazole with ruthenium(ii) polypyridine complexes to sense copper(ii) and sulfide ions

A bis-ruthenium(ii) polypyridyl complex was connected with a p-tert-butyl calix[4]arene platform (Ru2L) through 1,2,3-triazole and used as a luminescent probe to detect selected ions. Ru2L acted as a highly sensitive and selective turn off sensor towards Cu2+ ions in CH3CN/10 mM HEPES buffer (pH = 7.4) (8/2, v/v) medium. The detection limit of Cu2+ was found to be 4.11 μM. The Cu2+ ion binding with Ru2L showed a paramagnetic signal in EPR analysis. The ensemble (Ru2L-Cu2+) was investigated with a variety of anions, but only sulfide anions enhanced the emission intensity in the presence of other anions. The ensemble works as a turn-on sensor towards S2-via a metal ion displacement method to form stable CuS. The detection limit of S2- was estimated from the emission intensity to be 0.35 μM, which is an excellent result with respect to supramolecular platform based sensors in an aqueous medium. Ru2L also showed low cytotoxicity against human lung cancer cell line A549 and hence can be used in cell imaging.

Synthesis of 2,2-Bipyridines via Suzuki-Miyaura Cross-Coupling

For a long time, the Suzuki-Miyaura cross-coupling reaction could not be used for the synthesis of 2,2′-bipyridines due to the lack of sufficiently stable 2-pyridylboron compounds. Stabilized 2-pyridylboronic acid esters recently developed by Hodgson, however, were found to be ideally suited for this purpose. Two general protocols could be developed and demonstrated to be valuable alternatives, which can be used very efficiently for the synthesis of functionalized 2,2-bipyridines.

LUMINESCENT METAL COMPLEXES. PART 1. TRIS-CHELATES OF SUBSTITUTED 2,2'-BIPYRIDYLS WITH RUTHENIUM(II) AS DYES FOR LUMINESCENT SOLAR COLLECTORS

Ruthenium(II) and osmium(II) complexes of 2,2'bipyridyls (bipy) and 1,10-phenanthrolines (phen) are identified as feasible dyes for use in luminecsent solar collectors.Twenty-seven RuII)bipy)32+ complexes are prepared and the absorption and emission spectra of their solutions in EtOH-MeOH at room temperature are reported.Quantum efficiencies, wich are sensitive to oxygen quenching, vary between 0.002 and 0.306 depending upon substituents.The effect of the medium on the spectral properties of selected compounds has also been investigated.Measured quantum yields of non-aqueous solutions are higher than those for aqueous solutions but lower than for doped plastic films.
