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

Fluorescent dyes 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 synergy between the anchoring and diluting effect. In addition, the hybrids represent reversible transformation and tunable luminescence by different loading of the Rhodamine 6G dye within [Mo8O26]4- architecture. The 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.
