Resumen:
We report the synthesis of a smart novel hybrid with reversible photoswitchable luminescence properties modulated by light. Combination of a low molecular weight organgelator (LMOG) and CdSe/ZnS core-shell semiconductor nanoparticles capped with trioctylphosphine oxide ligands produces a luminescent, stable and transparent material. Modulation of the luminescence properties was succesfully achieved using a diarylethene photochromic compound, with good resistance to fatigue ca. 22 cycles. Interestingly, the morphology of the organogel fibers was preserved in the hybrid, while a partial luminescent quenching of the nanoparticle was observed. This material could have implication for on-and-off photoswitching applications.
