Electrochromic ultra-thin films based on cerium polyoxometalate

Effects of film structure on electrochromic properties of the multilayer films containing polyoxometalates

“…Electrochromic multilayers based on POMs and polyelectrolytes have been studied for several years, and many works have been reported [18][19][20][21][22][23]. It is noted that the conditions employed in building electrochromic LbL films based on POMs have been modified to distinct, individual patterns.…”

“…In that case, they improved the optical contrast and the response time by at least one order of magnitude compared with the former. More recently, we have been conducting detailed examination of the electrochromic performance of Dawson-type tungstophosphate and their derivatives [20][21][22][23].…”

Electrochemical sensor for detecting both oxidizing and reducing compounds based on poly(ethyleneimine)/phosphotungstic acid multilayer film modified electrode

“…So far, there were lots of investigations on the electrochemical behavior of LbL multilayer POMs films [12,13,25], such as poly (acrylamide)/phosphomolybdic acid, PEI/NaP 5 W 30 , PEI/(P 8 W 48 / Chitosan) 8 [26][27][28]. Here, the electrocatalytic reduction behavior of PEI/PTA multilayer film modified electrode was investigated using H 2 O 2 .…”

“…Recently, PTA based composite film received increasing attention due to its simplicity and efficiently. Till now, it has been reported that PTA/Nafion, PTA/Graphene oxide, PTA/Poly (2,5-dimethoxyaniline) and PTA/Chitosan composite films were prepared based on electrodeposition [7], self-assembled monolayer [8], spray pyrolysis [9] and Langmuir-Blodgett techniques etc. [10], and all of them showed great electrocatalytic activities [11][12][13][14].…”

Metallo-supramolecular modules as a paradigm for materials science

“…Recently, a dual-mode device was introduced that combines photochromic and electrochromic properties [126]. Several other systems have also been studied recently [127][128][129][130]. A large number of POMs undergo a series of reversible one-and two-electron reductions, which facilitates their use as redox catalysts [131].…”
