Photochromic and luminescent switchable iodoargentate hybrids directed by solvated lanthanide cations

Author affiliations

Abstract

Four iodoargentate hybrids, [Eu(DMSO)8]2[Ag2I5][Ag5I8] (1), [Eu(DMSO)8][Ag7I10] (2), [Tb(DMSO)8]2[Ag2I5][Ag5I8] (3) and [Tb(DMSO)8][Ag6I9] (4) (DMSO = dimethyl sulfoxide), have been rationally synthesized, which display simultaneous photochromic and luminescent switchable performances. Photochromism is due to the photolysis of iodoargentate anions and the consequent generation of Ag0 particles with surface plasmon resonance (SPR) absorption. Meanwhile, luminescent switchable performance is ascribed to intermolecular fluorescence resonance energy transfer (FRET) from fluorescent solvated lanthanide cations to photochromic iodoargentate anions.
