“…As for the previously considered examples [71,72] the PEI-(PGA-PLL) n films displayed a strong preferential incorporation (Figure 6) of the negatively charged CuPc-SO 4 with respect to the cationic CuPc-Py [73]. This finding is in perfect agreement with the expected positive Donnan potential of such films at pH 7.5.…”

“…Indeed it took almost 2 h to reach a steady frequency change of the quartz crystal coated with a PEI-(PGA-PLL) 8 film, of about 100 nm in thickness, put in contact with a 10 −3 M Cu(II) tetrasulfonato phtalocyanine (Cu-Pc-SO 4 ) containing solution [73]. …”

“…This means that electroneutrality is ensured by the preferential incorporation of one type of ions from the electrolyte solution in contact with the film [ 65 ]. This property allows such “exponentially growing films” to behave as ion exchange membranes, allowing for instance the incorporation of “colored” redox probes [ 66 , 67 , 68 ], drugs [ 69 ] and dyes [ 70 , 71 , 72 , 73 ]. In the investigation published by Burke and Barrett [ 71 ], the (PAH-HA) 10 films, where HA represents hyaluronic acid, were deposited from solutions at pH 3 and the film swelling was investigated under the influence of a pH change.…”

“…The binding kinetics of cationic and anionic phtalocyanines to (PLL-PGA) n films, where PGA denotes poly( L -glutamic acid) was investigated by means of quartz crystal microbalance with dissipation (QCM-D) monitoring and was found to be pretty slow ( Figure 5 ). Indeed it took almost 2 h to reach a steady frequency change of the quartz crystal coated with a PEI-(PGA-PLL) 8 film, of about 100 nm in thickness, put in contact with a 10 −3 M Cu(II) tetrasulfonato phtalocyanine (Cu-Pc-SO 4 ) containing solution [ 73 ].…”

Polyelectrolyte multilayer films are a versatile functionalization method of surfaces and rely on the alternated adsorption of oppositely charged species. Among such species, charged dyes can also be alternated with oppositely charged polymers, which is challenging from a fundamental point of view, because polyelectrolytes require a minimal number of charges, whereas even monovalent dyes can be incorporated during the alternated adsorption process. We will not only focus on organic dyes but also on their inorganic counterparts and on metal complexes. Such films offer plenty of possible applications in dye sensitized solar cells. In addition, dyes are massively used in the textile industry and in histology to stain textile fibers or tissues. However, the excess of non bound dyes poses serious environmental problems. It is hence of the highest interest to design materials able to adsorb such dyes in an almost irreversible manner. Polyelectrolyte multilayer films, owing to their ion exchange behavior can be useful for such a task allowing for impressive overconcentration of dyes with respect to the dye in solution. The actual state of knowledge of the interactions between charged dyes and adsorbed polyelectrolytes is the focus of this review article.
