Some of these surfactant-encapsulated polyoxometalate complexes exhibited liquid-crystaUine behavior. Paul and coworkers obtained room temperature LCs by complexation of the sandwiched europium-containing polyoxometalate [Eu(SiW9Mo2039)2] with a series of cationic surfactants (Zhang et al., 2005). For the quaternary ammonium cations with one long chain a hexagonal (columnar ) phase and possibly a cubic phase were observed, whereas for the quaternary ammonium cation with two long chains... 

The structural and spectroscopic features of the photoactive complex are preserved inside the polymeric film, as confirmed by UV-vis spectra. In addition, SEM analysis of both the film surface and cross-section highlight a well-dispersed, homogeneous distribution of the catalyst domains, which appear as spherical particles of approximately 1-2 xm in diameter. The structural similarity of (RfN)4Wio032 with other surfactant encapsulated polyoxometalates (SEPs) suggests the formation of organized domains, similar to spherical onion-like vesicles. ...
