چکیده
Synthesis of monosubstituted benzyl boronic acid viologen (mBBV) has been achieved. The group in mBBV can form ester bonds with the hydroxyl groups polyvinyl alcohol (PVA), resulting an all-in-one electrochromic gel. immobilized by slow down diffusion rate and effectively mitigate dimerization, which may address issues caused dimerization. optical contrasts mBBV-PVA reached 49.02% 45.01%, respectively. electrochemical properties obtained from tests suggest potential application field electrochromics.

Temperature-dependent structural evolution and electrochromic properties of peroxopolytungstic acid
Temperature-dependent in situ W L3-edge X-ray absorption spectroscopy has been performed at 20–500 ‡C to investigate the geometric environment and electronic structure of tungsten upon the transformation of electrochromic peroxopolytungstic acid to tungsten trioxide. The temperature-dependent variation of the coordination number and bond distance of the nearest (W–O) sphere reveals that the per...
متن کاملHigh-contrast solid-state electrochromic devices of viologen-bridged polysilsesquioxane nanoparticles fabricated by layer-by-layer assembly.
Water-soluble silsesquioxane nanoparticles (NPs) incorporating viologen groups (PXV; 1,1'-bis[3-(trimethoxysilyl)propyl]-4,4'-bipyridinium iodide) have been synthesized by sol-gel polymerization. The electrochromic properties of the bulk film fabricated by layer-by-layer (LbL) assembly have been examined, along with their incorporation into solid-state devices. The orange LbL films show high th...
متن کاملElectrochromic properties of self-organized multifunctional V2O5–polymer hybrid films
Bio-inspired V2O5–polymer hybrid films were prepared following a one-step self-organization procedure based on liquid crystal formation of organic and inorganic components. These materials were previously reported to exhibit advantageous mechanical properties, comparable to biomaterials, such as human bone and dentin. Here, we show that these hybrid films prepared via a fast and simple synthesi...

15 صفحه اولElectrochromic properties of TiO2 nanotubes coated with electrodeposited MoO3.
Despite a favourable morphology, anodized and ordered TiO2 nanotubes are incapable of showing electrochromic properties in comparison to many other metal oxide counterparts. To tackle this issue, MoO3 of ~5 to 15 nm thickness was electrodeposited onto TiO2 nanotube arrays. A homogenous MoO3 coating was obtained and the crystal phase of the electrodeposited coating was determined to be α-MoO3. T...
