Patent ID: 8598308

Claim:
A multifunctional dendron or dendrimer, comprising a one or more generations covalently bonded via convergent synthesis to a reactive site on a nucleus; wherein said nucleus has at least one reactive site in a dendron and at least two reactive sites in a dendrimer; wherein a first generation covalently bound to said nucleus and comprises at least 2 of the following structures: a spacer, a load, a branching element; wherein optional intermediary generations are covalently bound to said first generation or another intermediary generation, wherein said optional intermediary generations each comprises at least 2 of the following structures: a spacer, a load, a branching element; and a terminal generation which comprises at least 3 of the following structures: a spacer, a load, a branching element, and a terminal; wherein said first generation can be said terminal generation; wherein said load, spacer and branching element can be the same or different in said first generation, said intermediate generation or said terminal generation; and wherein said spacer is a molecule having a least two reactive sites, said load is a molecule having at least two reactive sites and a desired activity, and said branching element is a molecule having at least three reactive sites, and said terminal is any molecule having at least one reactive group, and wherein there is at least one load in said multifunctional dendron or dendrimer.
