Novel Ru^II Complexes with Bispidine‐Based Bridging Ligands: Luminescence Sensing and Photocatalytic Properties

Abstract

New ligands with a bidentate bipyridyl (bpy) and a tetradentate bispidine (bisp) subunit (bipyridyl = 2,2Ј-bipyridine derivative, bispidine = 3,7-diazabicyclo[3.

Core‐Shell Ag@TiO2 Nanocomposites for Low‐Power Blue Laser Enhanced Copper(I) Catalyzed Ullmann Coupling

“…Ligand L was synthesized in a few steps. Firstly, 4,4’‐dimethyl‐2,2’‐bipyridine was functionalized with one aldehyde group that allowed attachment of the phosphonate tether bearing oxyamine end‐groups (NH 2 O(CH 2 ) 3 P(O)(OEt) 2 ) in ethanol, via the formation of a stable O‐alkyloxime bond (‐C=N‐O‐). Then hydrolysis of the phosphonate ester using McKenna's method afforded ligand L (scheme ) in a good yield (for more details, see the supporting information).…”

Luminescent sensor for copper(II) ion based on imine functionalized monometallic rhenium(I) complexes

“…Re(CO)5Br was obtained by the oxidative addition of Br2 to Re2CO10 [48]. 4-Methyl-2,2-bipyridine-4-carboxaldehyde was synthesized by using previous literature procedure [49].…”

Synthesis, photophysical properties and spectroelectrochemical characterization of 10-(4-methyl-bipyridyl)-5,15-(pentafluorophenyl)corrole

“…The reaction to obtain the functionalized bipyridyl-aldehyde was based on the formylation reaction between 4,4 0 -(dimethyl) bipyridine (1.0 equivalent) and SeO 2 (1.3 equivalents) described by Busche and co-workers [27] (Scheme 1). After 24 h under reflux in dry 1,4-dioxane the functionalized aldehyde 1 was isolated in large scale (around 1-2 g; yield 35%).…”
