The present invention describes a process for preparing new looped dendrimer and dendron compounds by controlling the molar amount of branch cell reagent monomer that is combined with various cores bearing core- XR functionalities (e.g., primary, or secondary amines, thiol, or epoxy functionalities). These looped, macrocyclic structures are more robust to various conditions, with greater resistance to acid/base hydrolysis. Alternatively, the looped, macrocyclic structure may offer new orientations that would qualify it as a better chelation ligand for metals, and other similar uses. |
