• Dendrimers are molecularly uniform macromolecules with a highly symmetric structure. They are structurally derived from star polymers, with the individual chains each branched in a star shape. Dendrimers arise from small molecules through a repetitive sequence of reactions, resulting in ever-increasing branches, each terminating with functional groups, which in turn are the starting point for further branching. Thus, with each reaction step, the number of monomer end groups increases, resulting in a spherical tree structure at the end. A characteristic feature of dendrimers is the number of reaction stages used to build them up, commonly referred to as "generations.” Due to their uniform structure, dendrimers generally have a very narrow molecular weight distribution.
