    摘要: Macromolecules in the shape of three-dimensional kites, barbells, and other shapes are disclosed. The shaped macromolecules are prepared the reaction of one or more dendritic polymers and a linear polymer. The kite-shaped macromolecules are dendritic polymers attached at either their focal points or at an outer to a long carbon chain group. The barbell macromolecules have dendritic polymers at either end of the molecule, which polymers are connected together through the focal points of each by a suitable connecting substituent such as a linear polymer. The shaped macromolecules are used in specialty medical and technological applications including such as drug delivery agents, imaging materials, molecular devices, thin film devices, surface modifiers, transport agents, compatibilizers, rheology control agents, molecular ball bearings, molecular dipoles, non-linear optical materials, medical imaging agents, membrane and cell modifiers, complexing agents, adhesives, interface strengthening agents, and the like.
