Abstract
The emissive layered solid HUO2PO4·4H2O (HUP) readily undergoes intercalative ion exchange reactions with a variety of cationic species, leading, in many cases, to substituted lamellar materials which retain the luminescence characteristic of UO22+.1 We have recently carried out such substitution reactions using the following Cr(III) Werner complexes: Cr(NH3)63+; Cr(NH3)5(H2O)3+; Cr(ethylenediamine)33+ (Cr(en)33+); Cr(2,2′-bipyridine)33+(Cr(bpy)33+); and Cr(urea)63+.
