Abstract
An anisolyl-picolinate antenna grafted onto different macrocyclic ligands such as tacn, pyclen, or cyclen renders the resulting terbium(III) complexes highly sensitive to oxygen in aqueous solutions, enabling the design of ratiometric or lifetime-based molecular sensors. The underlying sensitization mechanism was investigated using analogous gadolinium(III) complexes, and the oxygen sensitivity was studied using transient absorption spectroscopy. The antenna-based triplet lifetime increased by up to 900-fold upon degassing, underscoring the role of the ligand excited states in designing highly sensitive oxygen probes.
期刊介绍:
Inorganic Chemistry publishes fundamental studies in all phases of inorganic chemistry. Coverage includes experimental and theoretical reports on quantitative studies of structure and thermodynamics, kinetics, mechanisms of inorganic reactions, bioinorganic chemistry, and relevant aspects of organometallic chemistry, solid-state phenomena, and chemical bonding theory. Emphasis is placed on the synthesis, structure, thermodynamics, reactivity, spectroscopy, and bonding properties of significant new and known compounds.
