Microviscosity in the cavities of titania gels studied by steady-state fluorescence anisotropy

A series of fluorescent compounds (rhodamine 101, cresyl violet, oxazine 1, and tris(2,2′-bipyridyl)-ruthenium(II) chloride hexahydrate) were used as molecular probes in titania gels. Sols and gels of pH = 2.5 and 3.5 were prepared using standard methods. Absorption and emission spectra and fluoresc...
