Layered monomer assemblies

Going further into the mechanism and kinetics of mono-layer self-assembly at the mineral-water interface, in situ vibrational sum-frequency spectroscopy (VSFS) has been used to investigate the adsorption, desorption, and equilibrium monomer exchange processes of sodium dodecanoate at the fluorite(CaF2)-water interface. ... 

The differences in the final properties of the copolymer according to the monomer s feed ratio were also observed for P(DHQT-co-DNBP) (12) films electrodeposited onto ITO/glass. DHQT is a fluorescent thiophene oligomer usually applied as active layer for assemble of organic field effect transistors (OFETs)/ photovoltaic cells and electrochromic devices/ while the polymer PDNBP and its copolymer with EDOT have... 

In reconstitution experiments, the self-assembly of the pore-forming protein a-hemolysin of Staphylococcus aureus (aHL) [181-183] was examined in plain and S-layer-supported lipid bilayers. Staphylococcal aHL formed lytic pores when added to the lipid-exposed side of the DPhPC bilayer with or without an attached S-layer from B coagulans E38/vl. The assembly of aHL pores was slower at S-layer-supported compared to unsupported folded membranes. No assembly could be detected upon adding aHL monomers to the S-layer face of the composite membrane. Therefore, the intrinsic molecular sieving properties of the S-layer lattice did not allow passage of aHL monomers through the S-layer pores to the lipid bilayer [142]. 

One aspect of polyelectrolytes that has received a lot of attention in recent years is their utilization in the assembly of multilayered stmctures, which are formed via alternating adsorption of oppositely charged polymers. Using a terpy-end-capped ditopic monomer with, for example, Fe salts, Schiitte et al. (1998) demonstrated that MSPs can be utilized in a layer-by-layer assembly with polyanions such as poly(styrene sulfonate). 

More recent efforts focused on surface modification of conductive polymers by the SECM, fabrication, and characterization of microstructures. Mandler et al. developed an approach for the formation of a 2D conducting polymer on top of an insulating layer. This approach, based on electrostatically binding a monomer (anilinium ions) to a negatively charged self-assembled monolayer of co-mercaptodecanesulfonate [MDS, HS(CH2)ioS03 ] followed by its electrochemical polymerization. The polyanion monolayer exhibited the properties similar to those of a thin polymer film [167].
