Journal ArticleDOI
Photophysics and photochemistry of oxygen sensors based on luminescent transition-metal complexes
TL;DR: A detailed study of the photophysics and photochemistry of polymer-immobilized luminescent transition-metal complex is presented in this paper, where the authors focus on understanding the underlying origin of the nonlinear Stern-Volmer quenching response.
Journal ArticleDOI
Multi-emissive difluoroboron dibenzoylmethane polylactide exhibiting intense fluorescence and oxygen-sensitive room-temperature phosphorescence.
TL;DR: It is reported that unusual room-temperature phosphorescence is achieved by combining a classic boron dye, difluoroboron dibenzoylmethane, BF2dbm, with poly(lactic acid) (PLA), a common biopolymer, resulting in a highly sensitive single-component oxygen sensor.

Determination of oxygen concentrations by luminescence quenching of a polymer-immobilized transition-metal complex
John Roger Bacon,James N. Demas +1 more
TL;DR: Oxygen quenching of the luminescence of tris(4,7-diphenyl-1,10-phenanthroline)ruthenium(II) perchlorate immobilized in a silicone rubber is shown to be an accurate and precise method for measuring oxygen concentrations in solutions and in the gas phase.
