Versatility of the ionic assembling method to design highly luminescent PMMA nanocomposites containing [M6Qi8La6]n− octahedral nano-building blocks.

New luminescent poly(methylmethacrylate) (PMMA) nanocomposites with high content of different hexanuclear octahedral cluster building blocks, namely [Mo₆I₈(C₂F₅COO₆)]²⁻, [Re₆Se₈(CN)₆]⁴⁻ and [W₆Cl₁₄]²⁻ have been prepared by free-radical polymerisation. To do so, cluster complexes bearing a polymerisable ammonium counter-cation have been synthesised. In this way, we demonstrate that ionic assembling is a powerful tool to functionalise easily any type of anionic cluster units to be introduced in a PMMA organic matrix. All samples remain homogeneous, stable during several months, and retain the luminescence properties of the cluster precursor. [ABSTRACT FROM AUTHOR]
