Journal Article
Walter, E. R., Williams, J. G., & Parker, D. (2017). Solvent polarity and oxygen sensitivity, rather than viscosity, determine lifetimes of biaryl-sensitised terbium luminescence. Chemical Communications, 53(100), 13344-13347. https://doi.org/10.1039/c7cc08361k

In a macrocyclic terbium complex incorporating a biaryl sensitiser, the observed variation of emission lifetime is shown to be determined by the solubility of oxygen in the solvent system and the relative energy of the chromophore excited state, rath...
