Luminescence Properties of Self-Aggregating TbIII-DOTA-Functionalized Calix[4]arenes

Self-aggregating calix [4] arenes carrying four DOTA ligands on the upper rim for stable
complexation of paramagnetic GdIII-ions have already been proposed as MRI probes. In this
work, we investigate the luminescence properties of TbIII-DOTA-calix [4] arene-4OPr
containing four propyl-groups and compare them with those of the analog substituted with a
phthalimide chromophore (TbIII-DOTA-calix [4] arene-3OPr-OPhth). We show that, given its
four aromatic rings, the calix [4] arene core acts as an effective sensitizer of Tb-centered …
