  Use of fluorescent probes for the investigation of solutions: the case of europium—carboxymethoxysuccinate complexes

  摘要：

  The investigation of Eu-cmos solutions frozen in liquid nitrogen performed under site-selective excitation and with time-resolved detection shows the existence of three different species, each characterized by one particular set of spectroscopic features (5D2 sublevels energy scheme + 5D0 --> F-7(0) emission position + 5D0 lifetime). The relative occurrence of the three species varies with the Eu:cmos ratio. In the liquid state only two 0 --> 0 lines attributed respectively to Eu(cmos) . nH2O and Eu(cmos)2 . n'H2O are observed. We have checked by comparison with frozen EuCl3 aqueous solutions that Eu3+ (aquo) is not the third species existing at LNT. We discuss its attribution to oligomeric species yet detected in Tb-cmos solutions and the influence of the ice structure on the spectroscopic characteristics of Eu3+-ligand frozen solutions.
