      Nanocomposites with a LaF3:Yb,Er core and a mesoporous silica shell structure have been developed. These multifunctional photoluminescent composite materials were tested as drug carriers to investigate their drug storage/release properties. The green upconversion photoluminescence of these LaF3:Yb3+, Er3+@nSiO2@mSiO2 nanocomposites is useful for tracking and monitoring the drug release.

      New coordination polymers [(Cp*2Mo2P2Se3)(CuX)3(CH3CN)]n (Cp* = C5Me5; X = Cl, Br, I) have been prepared. A competitive coordination of Cu towards P and Se is observed that is completed by weak intermolecular Se···Se interactions to give 2D networks. Addition of P4Se3 as a competitive reagent gave [(Cp*2Mo2P2Se3)(P4Se3)(CuX)2]n, a new type of organometallic–inorganic hybrid polymer.
