摘要： This invention provides a cost effective process and new Janus dendrimers where at least two dendrons are attached at the core (with or without a connector group) and where at least two of the dendrons have different functionality. Preferred are those Janus dendrimers where at least one dendron is a PEHAM dendron. Thus these Janus dendrimers are heterobifunctional in character and use unique ligation chemistry with single site functional dendrons, di-dendrons and multi-dendrons. Also included are Janus dendrons which may be used as intermediates to make the Janus dendrimers or to further react with another reactive moiety. These Janus dendrimers can provide several new dendrimer moieties, namely: combinatorial libraries of bifunctional structures; combined target director and signaling dendrimers; specific targeting entities for diagnostic and therapeutic applications, such as for example targeted MRI agents, targeted radionuclide delivery for diseases such as cancer, and targeted photosensitive or radiowave sensitive agents.

摘要： Dendritic polymers with enhanced amplification and interior functionality are disclosed. These dendritic polymers are made by use of fast, reactive ring-opening chemistry (or other fast reactions) combined with the use of branch cell reagents in a controlled way to rapidly and precisely build dendritic structures, generation by generation, with cleaner chemistry, often single products, lower excesses of reagents, lower levels of dilution, higher capacity method, more easily scaled to commercial dimensions, new ranges of materials, and lower cost. The dendritic compositions prepared have novel internal functionality, greater stability (e.g., thermal stability and less or no reverse Michael's reaction), and reach encapsulation surface densities at lower generations. Unexpectedly, these reactions of polyfunctional branch cell reagents with polyfunctional cores do not create cross-linked materials. Such dendritic polymers are useful as demulsifiers for oil/water emulsions, wet strength agents in the manufacture of paper, proton scavengers, polymers, nanoscale monomers, calibration standards for electron microscopy, making size selective membranes, and agents for modifying viscosity in aqueous formulations such as paint. When these dendritic polymers have a carried material associated with their surface and/or interior, then these dendritic polymers have additional properties for carrying materials due to the unique characteristics of the dendritic polymer, such as for drug delivery, transfection, and diagnostics.

摘要： 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.

摘要： Poly(ester-acrylate) and poly(ester/epoxide) dendrimers. These materials can be synthesized by utilizing the so-called “sterically induced stoichiometric” principles. The preparation of the dendrimers is carried out by reacting precursor amino/polyamino-functional core materials with various branch cell reagents. The branch cell reagents are dimensionally large, relative to the amino/polyamino-initiator core and when reacted, produce generation=1 dendrimers directly in one step. There is also a method by which the dendrimers can be stabilized and that method is the reaction of the dendrimers with surface reactive molecules to pacify the reactive groups on the dendrimers.

摘要： Specific PEHAM dendrimers are used in a formulation with an active agent for agricultural purposes, particularly for increasing the efficacy of the active agent in various ways, such as by improving solubility of the active agent in the formulation, by improving adhesion and penetration of the active agent to plant surfaces, by improving the water-fastness of the active agent to the plant or seed, by increasing soil penetration of the active agent to reach the plant roots or under soil parts, or by reducing soil adhesion of the active agent to reach the plant roots or under soil parts, or reducing enzymatic degradation of the active agent by the plant or seed or microorganisms in the soil.
