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.
本发明描述了一种通过控制与带有核心-XR功能基团(例如,主要或次要胺基,硫醇或环氧基团)的各种核心结构相结合的支链细胞试剂单体的摩尔量来制备新的环形树状分子和树状化合物的过程。这些环形的大环结构在各种条件下更加稳健,对酸碱水解有更强的抵抗力。另外,这种环形的大环结构可能提供新的取向,使其成为更好的金属螯合配体以及其他类似用途的合适选择。
