Abstract: Dendrimer is a compound word, composed of the Greek "dendron", meaning tree and the word "polymer", that itself is a fusion of the Greek "poly" (many) and "meros" (part). Dendrimers can be divided in three zones: The region of the initiator core, the region of the inner branching units and the outer level, carrying the endgroups. Figure 1 shows the building of a two dimensional Dendrimer. The chemistry of the Dendrimers is a modern and new working field, that brought out a lot of interesting and aesthetic molecules. In future the synthesis of further interesting structures can be expected. The first work [1] initiated a great, almost exponentially, growing number of publications [2]. This new field of research is of academic interest and the industrial research hopes of new positive properties belonging to this new class of molecules, too
