“…Because of the increasing screening of charges along the polyelectrolyte chain with increasing ionic strength, the change of the NaCl concentration in the polyelectrolyte strongly influences the assembly of the multilayer 44, 45. The UV absorption spectra of the multilayer show all of the PAH/PSS films deposited at different concentrations of NaCl grow linearly with the number of bilayers, and all of the PAH/PSS films deposited at different concentrations of NaCl grow exponentially with the number of bilayers.…”

“…[44,45] The UV absorption spectra of the multilayer show all of the PAH/PSS films deposited at different concentrations of NaCl grow linearly with the number of bilayers, and all of the PAH/PSS films deposited at different concentrations of NaCl grow exponentially with the number of bilayers. For the same number of bilayers, the mass of both the PAH/PSS film and the PDDA/PSS film increase with NaCl concentration in the range from 0.1 to 2.0 mol Á L À1 .…”

A mathematical expression describing the growth regime of multilayers formed layer by layer and the correlation between the nature of the growth process and the distribution of the charges in the polyelectrolyte deposited on the surface of the film is reported. Two typical polyelectrolyte pairs were chosen such that one of them causes the film to grow linearly while the other causes the film to grow exponentially. The growth processes were monitored by UV‐Vis spectrophotometry and the experimental data was analyzed. The influence of the polyelectrolyte and NaCl concentration on the fabrication of PAH/PSS and PDDA/PSS films is discussed by analyzing the change of model parameters.

“…Moreover, two intense t as (Mo-O-Mo) peaks at 875 and 808 cm À1 changed into two weak peaks at 864 and 825 cm À1 after UV irradiation, suggesting that the partial transformation from ionic bond to covalent bond between the oxygen atom from Mo-O-Mo bond of PMo 12 and the carbon atom from cationic intermediate of DR has arisen, as illustrated in . In this work, the inference of the partial formation of covalent bond related with diazo group could also be supported by some examples from the literature [24]. Before UV irradiation, the inherent property of [PMo 12 O 40 ] 3À anion could basically remain, though there is an electrostatic interaction between [PMo 12 O 40 ] 3À anion and -N 2 + group of DR. After UV irradiation, a little reduction of [PMo 12 O 40 ] 3À anion may occur accompanying with the partial formation of covalent bond; this could be indicated by appearance of a week broad peak at about 800 nm in UV-Vis spectrum.…”

“…79,80 This method may find application in the fabrication of stable sensor devices, patterned surface structures and ultrathin films for corrosionresistant coatings. For example, covalently attached multilayer films of DAR and porphyrin and phthalocyanine formed on electrode surfaces can significantly improve the lifetime of resulting sensors of chemically modified electrodes.…”

Layer-by-layer (LbL) assembly is a powerful means for fabricating multilayer thin films with controlled architecture and composition. This feature article discusses different types of methods for LbL assembly. On the one hand, some of the conventional LbL methods are introduced, which are driven by electrostatic interactions, hydrogen bonds, step-by-step reactions, sol-gel processes, molecular recognition, charge-transfer, stepwise stereocomplex assembly, and electrochemistry. On the other hand, some of the unconventional methods for fabricating of the building blocks which can not be assembled by conventional methods are also summarized. These unconventional methods usually involve the formation of supramolecular structures via one type of self-assembly. These structures can subsequently be used as building blocks in another type of self-assembly. To take advantage of these conventional and unconventional methods, a great number of building blocks can be fabricated into multilayer thin films with a defined sequence structure in a designed way. It has been demonstrated that LbL methods provide new horizons for surface molecular engineering.
