DOI: 10.1002/cplu.202000034
Abstract: An unusual thermally sensitive anion-cation interaction, which is characteristic of the anion [Eu(FOD)4 ]- , occurs in the complex [CHOL][Eu(FOD)4 ] (1; CHOL=choline; FOD=1,1,1,2,2,3,3-heptafluoro-7,7-dimethyl-4,6-octanedionate) and affects both quantum yield and thermochromic behavior. This prompted the… read more here.
