Photochromic inorganic–organic multilayer films based on polyoxometalates and poly(ethylenimine)

“…It should be pointed out that the multilayer containing POMs can be considered as a composite material, which does not have obvious interfaces between the polyelectrolyte and inorganic component. Similar surface morphology was also observed in NaP 5 W 30 /PEI multilayers [21]. …”

“…The change in the absorbance of (NaP 5 W 30 /PEI) 30 film (0.022 unit at 800 nm, Ref. [21]) is larger than that of (W 10 /PEI) 30 film (0.015 unit at 800 nm, Fig. 5b) after UV irradiation for 10 min.…”

“…Very recently, we found that photochromic inorganicorganic multilayer films could be obtained by incorporation of POMs [21]. Chen et al fabricated photochromic superlattice films by the LbL technique [22], which was based on metal oxides and organic molecules.…”

Covalent assembly of shortened multiwall carbon nanotubes on polyelectrolyte films and relevant electrochemistry study

“…FTIR spectroscopy is an effective and commonly used method to characterize and identify the structure and composition of organized molecular film [29,30]. Here the na- ture of the driving force for the self-assembly process was studied by this means in the absorbance mode (see Fig.…”

Dye–polyoxometalate composite films: Self-assembly, thermal and photochemical properties

“…When POMs are used to fabricate ultrathin films, their properties will be incorporated into the films and the application of POMs will be convenient. As versatile inorganic building blocks, POMs have been used as anions for the construction of functional thin films via LbL self-assembly method [29][30][31][32][33][34][35][36][37][38]. In these reports, the charge-balancing cations among multilayers are generally polyelectrolytes such as poly(diallyldimethylammonium chloride) (PDDA) and poly(allylamine hydrochloride) (PAH) [29,38].…”
