Weener et al. prepared photo-responsive monolayers from azobenzene modified polypropylene imine) dendrimers which also hold promise in the area of optical data storage [74], A fifth generation polypropylene imine) dendrimer was functionalized with equal amounts of palmitoyl and azobenzene containing alkyl chains, resulting in the formation of an amphiphilic copolymer with a random shell structure (Figure 16.5). 

The ability of azobenzene derivatives to isomerize in the CD cavity with good yields stimulated the preparation of Langmuir-Blodgett films, based on amphiphilic modified CDs, including aromatic azo compounds, with excellent photochromic properties [306].

In another field of current activity, the aggregation behavior of amphiphile molecules is modified and controlled by photoswitching of azobenzenes that are covalently linked as a component of some part or all the amphiphilic molecules. Japanese workers collected a large amount of data on photosensitive artificial membranes based on azobenzene derivatives. ...
