[Eu(L1)]. A complete 1H‐NMR relaxometric study was carried out for the octacoordinated [Gd(L1)] and [Gd(L2)] complexes. A remarkably long H2O residence lifetime (298τM=5.2 μs) was found by 17O‐NMR in the case of [Gd(L1)]. Micelle formation of the lipophilic complex [Gd(L2)] was evidenced, the critical micellization concentration (cmc) determined, and relaxometric properties of the system investigated
