The mechanical strain induced fluorescence lifetime variation in hybrid bistable [Fe(H-trz)<sub>2</sub>(trz)]BF<sub>4</sub>@SiO<sub>2</sub>@pyrene nanoparticles.
Nanocomposite spin crossover materials with gold nanoparticles were synthesized and plasmon-enhanced photothermal state switching was evidenced using Raman spectroscopy.
[Fe(Htrz)2(trz)]BF4@SiO2 nanorods were synthesized using a reverse emulsion technique and Tb(3+) complex was chemically bound to the silica surface. This Tb-spin crossover nanocomposite demonstrates high luminescence stability under continuous thermal cycling. A reabsorption mechanism is determined be responsible for intensity variation during spin state switching of iron complex.
We report on a thermochromic paper with reverse printing performance.
The working principle of a new kind nanothermometer is experimentally demonstrated using bistable materials with thermal memory. This thermometry approach allows for acquiring sub-wavelength resolution images fast, transient heating events.
Composite materials made of cellulose fibers and spin crossover micro-particles investigated by dynamic mechanical analysis revealed an abrupt reversible stiffening upon transition from the low to high state.
Nanocomposite materials containing Cadmium Telluride (CdTe) nanocrystals and [Fe(H-trz)2(trz)]BF4 nanoparticles were synthesized investigated for the coupling between their photoluminescent spin crossover properties. The bright CdTe emission around 550 nm was found to decrease reversibly when switching ferrous complex from high (HS) low (LS) state, which attributed spectral overlap of luminescence with absorption in latter electronic configuration. A significant irreversible change signal...
Isolated nickel nanoparticles in suspension or supported on silica are efficient catalysts for inactivated alkene hydrosilylation.
Topographic images of [Fe(Htrz)₂(trz)](BF₄) nanoparticles were acquired across the first-order spin transition using variable-temperature atomic force microscopy (AFM) in amplitude modulation mode. These studies revealed a complex morphology particles consisting aggregates small nanocrystals, which expand, separate and re-aggregate due to mechanical stress during spin-state switching events. Both reversible (prompt or slow recovery) irreversible effects (fatigue) on particle evidenced...
