Controlled assembly and reversible transformation of tuneable luminescent Mo8-R6G hybrids

Abstract

Fluorescent dyes such as rhodamine R6G usually suffer from quenching caused by aggregation in the solid state. Herein, we enhance the solid state luminescence of R6G by controlling assemblies of rhodamine R6G and [Mo₈O₂₆]⁴⁻ based on the synergies between the anchoring and diluting effects. In addition, the hybrids represent reversible transformation and tunable luminescence by different loadings of the rhodamine 6G dye within the [Mo₈O₂₆]⁴⁻ architecture. This work provides new ideas for the structural design, synthesis and transformation of POM-based hybrid materials, opening the way towards the design of novel multifunctional hybrid systems.
