Visible light induced electron transfer and long-lived charge separated state in cyanine dye/layered titanate intercalation compounds

Article Abstract:

Long-lived charge separated state induced by visible light via guest-to-host electron transfer is revealed in cyanine dye/layered titanate intercalation compounds where the J-aggregates of the cyanine dyes effectively acted as sensitizers. The stability of the charge separated state is rationalized by slow electron diffusion in the conduction band of the hosts as well as the nanostructure of the intercalation compounds.

Luminescence of tris(2,2'-bipyridine)ruthenium(II) cations ([[Ru[(bpy).sub.3].sup.2+]) adsorbed in mesoporous silicas modified with sulfonated phenethyl group

Article Abstract:

The investigation the variation of the position and the intensity of the luminescence of the adsorption of tris(2,2'-bipyridine)ruthenium(II) ([[Ru[(bpy).sub.3]].sup.2+]) complex cation into modified mesoporous silicas suggest that the average distance between the adjacent ([[Ru[(bpy).sub.3]].sup.2+]) changed with the loading amounts.
