Enabling the use of hydrophobic functional luminophores in aqueous media broadens the range of viable candidates for luminescent probes. In this study, photophysical properties of a camphor\u2010derived Eu(III) complex with hydrophilic ligands, [Eu(+tfc)\n                    <jats:sub>3<\/jats:sub>\n                    (TEGPO)\n                    <jats:sub>2<\/jats:sub>\n                    ] (tfc: 3\u2010(trifluoroacetyl)camphor, TEGPO: tetraethylene glycol monomethyl ether\u2010modified triphenylphosphine oxide) in methanol\u2013water media with various water fractions (\n                    <jats:italic>\n                      f\n                      <jats:sub>w<\/jats:sub>\n                    <\/jats:italic>\n                    ) are demonstrated. The Eu(III) complex showed aggregate formation and homogeneous dispersion in high\u2010water fractions (\n                    <jats:italic>\n                      f\n                      <jats:sub>w<\/jats:sub>\n                    <\/jats:italic>\n                    \u2265 50 vol%). The Eu(III) aggregates exhibited red emission, even though the complex showed little emission without aggregation. The emission intensity was enhanced depending on the water fraction. The luminescent lifetime was also extended by aggregation, which was attributed to the suppression of nonradiative relaxation pathways. Analysis of the photophysical parameters of the Eu(III) complex indicated that the emission enhancement mainly occurred because of suppression of nonradiative processes upon aggregate formation. This study provides a new design strategy for luminescent probes in aqueous media using camphor\u2010derived lanthanide complexes.\n
