Schematic depiction of the general structure of the dendritic scaffolds synthesized on solid support. The dendrons comprise terminal maleimide functionalities for the efficient Michael addition of arbitrary thiol-bearing molecules, symmetrical branching units, oligoethyleneglycols of differing lengths for modular molecular design and tailored distances between two adjacent dendron surface functionalities as well as the possibility to introduce a chelator or thiol functionality for radiometal labeling or biomolecule conjugation, respectively.
