Abstract The aggregation‐induced phosphorescence emission (AIPE) phenomenon (emergence or increase in intensity as a result of aggregation phosphorescent emitters) is regarded nowadays an effective tool for improving brightness and tuning photophysical properties phosphors. intrinsic drawback the aggregates featuring AIPE—their instability aqueous dispersions, which hampers their utility biomedical applications—can be overcome by stabilization inside block copolymer micelles. Herein, we...
Abstract In this work, two new biscyclometalated Ir(III) complexes with diimine ligands were synthesized. The compounds characterized by 1D and 2D NMR spectroscopy HR ESI mass spectrometry. All exhibit efficient phosphorescence pronounced sensitivity to the presence of oxygen. photophysical properties obtained compounds, including absorption, emission spectra, lifetimes quantum yields measured in various aqueous model biological media variations pH, temperature at O 2 concentrations. a very...
Monitoring of intracellular pH is great importance since deviation this parameter from the "normal" magnitudes can be considered as an indicator various pathologies. Thus, development new efficient and biocompatible sensors suitable for application in biological systems capable quantitative estimation remains urgent chemical task. Herein, we report synthesis a series phosphorescent rhenium [Re(NN)(CO)
In the present work, we described preparation and characterization of micelles based on amphiphilic poly(ε-caprolactone-
Abstract In the present report, a novel dual pH‐O 2 sensor based on covalent conjugate of rhodamine 6G and cyclometalated iridium complex with poly(vinylpyrrolidone‐ block ‐vinyltetrazole) copolymer is reported. model physiological solutions chromophores display independent phosphorescent fluorescent lifetime responses onto variations in oxygen concentration pH, respectively. Colocalization studies Chinese hamster ovary cells demonstrate preferential localization endosomes lysosomes. The...
