Stable multilayer films based on photoinduced interaction between polyoxometalates and diazo resin

Hybrid Materials Based on the Embedding of Organically Modified Transition Metal Oxoclusters or Polyoxometalates into Polymers for Functional Applications: A Review

“…After the initial absorption of the anionic clusters onto the positively charged polymer interface, UV irradiation was employed to foster the photodecomposition of the diazo resin, with loss of N 2 , and the photoreduction of the POM. The enhanced stability against solvent etching was explained by the formation of strong Mo-O-C interactions [ 250 ].…”

Assembly of 12-tungstosilicic acid and 4-aminobenzo-15-crown-5 ether based on the electrostatic attraction through bridging of oxonium ions on different substrates

“…FTIR spectral signatures can demonstrate whether the hydrate complex is present. The FTIR spectra of (SiW 12 ) 15 /(4-AB15C5) 14 on a PAH-coated CaF 2 plate using PAH/CaF 2 as the baseline are shown in Fig. 6.…”

“…The developing functional materials with relevant properties of POMs in film chemistry are catalytic activity [3,4], sensitive probe [5], magnetism [6,7], as well as thermochromism, photochromism, electrochromism, and luminescence [8][9][10][11]. There are several main strategies to build up POMscontaining multilayers, including Langmuir-Blodgett (LB) technique [7,8], electrochemical method [12], electrostatic layer-by-layer (LBL) self-assembly method [13] and photoinduced interaction between POMs and photosensitive polymers [14]. Among them, LBL method based on electrostatic attraction [15] is applied most widely to fabricate POMs-containing multilayer films.…”

“…Among them, LBL method based on electrostatic attraction [15] is applied most widely to fabricate POMs-containing multilayer films. Multilayer films consisting of POMs and polyelectrolyte were widely investigated in previous works [13,14]. Recently, the assembly of POMs with small molecules and their applications are largely made by LBL method [16].…”

“…FTIR spectra of 4-AB15C5 powder (a), SiW 12 powder (b) in KBr pellet, and (SiW 12 ) 15 /(4-AB15C5)14 deposited on the PAH-coated CaF 2 substrate using PAH/CaF 2 as baseline (c).…”
