Emission properties of [Eu(hfa)3(phen)] and [Eu(hfa)3(TPPO)2] dispersed in a fibrous network comprising p-chlorophenol plus AOT organogels

The rare-earth complexes [Eu(hfa)(3)(phen)] and [Eu(hfa)(3)(TPPO)(2)]were dispersed in the fibrous network structure of an organogel of phenol and surfactant AOT. Steady-state and time-resolved emission properties arising from the complex-organogel interactions of these two complexes were investigated. The results suggest that [Eu(hfa)(3)(phen)] localizes around the fibrous structure of the organogel architecture, whereas [Eu(hfa)(3)(TPPO)(2)] favors the solvent domain even when dispersed in the gel environment. These properties characterize the steady state and time -resolved behavior in the emission processes of the [Eu(hfa)(3)(phen)] and [Eu(hfa)(3)(TPPo)(2)] complexes, which can be regarded as gelaphilic and solvophilic, respectively.
