|a The multicomponent transfer of functional molecules by Langmuir-Blodgett (LB) technique onto solid substrates offers an interesting route for generation of functionalized patterns by self-assembly over large surface areas. In the present paper, we discuss LB transfer of mixed LB films containing different functional amphiphiles (an azide, an estrone derivate, a lithocholic acid derivative, or an alkoxyamine) in combination with dipalmitoylphosphatidyl choline (DPPC). The effect of the mixing ratio on pattern formation is discussed, and we provide some general design rules for the synthesis of functional molecules to be applicable for the multicomponent LB transfer process. We show that these functional compounds can be successfully transferred to oxidized Si wafers in stripe pattern. Covalent attachment of the functional entities is easily achieved, and the patterned surfaces are then ready for further chemical manipulation. This is demonstrated by site-specifically covalent attaching dye molecules applying the copper(l)-catalyzed alkyne azide click reaction (CuAAC), the thiol-ene reaction, and a surface-initiated radical polymerization
