Verani and coworkers widely investigated stimuli-responsive soft materials with interesting optical and redox behaviors. Such materials are able to self-assembly in functional ordered structures, as Langmuir-Blodgett films and liquid crystals, and possess potential applications in molecular electronics and magnetic films as well. These compounds are mainly based on Co(II) (94), Co(III) (95), Cu(II) (96), Fe(II)/Fe(III) (97), and Ni (II) and Zn(II) (98). A recent overview dedicated to colloidal systems, and their application in different fields has recently appeared in the literature (99). 

Langmuir-Blodgett films may have value in many applied areas of traditional interest to the industrial chemist, such as adhesion, encapsulation, and catalysis. The permeability characteristics of monolayer assemblies may also find application as synthetic membranes for ultrafine filtration, gas separation, and reverse osmosis. For example, Albrecht et al. (44) proved the eflSciency of polymeric diacetylene monolayers on semipermeable supports in reducing the flow of CH4. One interesting possibility lies in using LB monolayers as lubricants in magnetic tape technology. Unpublished reports have indicated that frictional coeflScients can be reduced markedly when the tape is coated with a few monolayers. In applications such as those listed previously, difiSculties may well be encountered with the mechanical stability of the films. To date, relatively little research has been carried out in this area.

Magnetic field effects on charge recombination reactions in porphyrin-viologen systems have been observed in solution and in Langmuir-Blodgett monolayers [190, 201, 202]. Photovoltaic effects have also been observed in such films, and these have been used to initiate hydrogen evolution from platinized films [193, 195].
