Thiol-reactive luminescent chelates of terbium and europium.
Thiol-reactive lanthanide complexes have been synthesized that are luminescent when bound to terbium and/or europium. The complexes consist of a diethylenetriaminepentaacetate (DTPA) chelate covalently joined through one amide bond to a chromophore, carbostyril 124, and via a second amide bond to a maleimide, bromoacetamide, or pyridyldithio moiety. Site-specific attachment and characterization...
متن کاملHighly luminescent lanthanide complexes with novel bis-β-diketone ligand: synthesis, characterization and photoluminescent properties.
A biphenyl-linked bis-β-diketone ligand, 3,3'-bis(3-phenyl-3-oxopropanol)biphenyl (BPB) has been prepared for the syntheses of a series of dinuclear lanthanide complexes. The ligand bears two benzoyl β-diketonate sites linked by a 3,3'-biphenyl spacer. Reaction of the doubly negatively charged bis-bidenate ligand with lanthanide ions forms triple-stranded dinuclear complexes Ln(2)(BPB)(3) (Ln=N...
متن کاملVoltammetric analysis of europium at screen-printed electrodes modified with salicylamide self-assembled on mesoporous silica.
Mercury-free sensors for europium (Eu(3+)) assay based on the chemical modification of screen-printed carbon electrodes (SPCEs) with self-assembled salicylamide on mesoporous silica (Sal-SAMMS) have been developed. The preconcentration of Eu(3+) at SAMMS-based sensors utilizes the binding affinity of the salicylamide and Eu(3+), accomplished at open circuit potential without electrolyte and sol...
متن کاملUltrabright fluorescent mesoporous silica particles
Recent self-assembly of ultra-bright fluorescent colloidal mesoporous (nanoporous) silica particles is highlighted. The particles can be up to two others of magnitude brighter than polymeric particles of comparable size assembled with quantum dots. Comparing with the maximum fluorescence of free dye in the same volume, the particles can show fluorescence which is higher by more than three order...
