| Abstract;Numerous analytical techniques consistently show that carbon-bound halogens (C-X,X=Cl,Br,I) can work as electron acceptor motifs in the formation of attractive interactions (C-X...El) with lone pair possessing atoms (El=N,O,S) which work as electron donor motifs. Here we describe how iodo- and bromoperfluorocarbons undergo a self-assembling process with hydrocarbon derivatives containing neutral or anionic electron donor sites (e.g. nitrogen, oxygen, sulphur atoms or halide, sulphide anions, respectively). The self-assembling process is driven by the "halogen bonding" namely an electron donation from the basic site on the HC module to the acid site on the PFC module. It will be described how the halogen bonding is an effective and reliable tool in crystal engineering to drive the self-assembly of PFC and HC molecules and it will be described how the implications of this interaction extend in all the fields where design and manipulation of aggregation processes play a key role.
