Introduction Over the past several years, advances in polymer chemistry have opened new avenues in the preparation of macromolecules possessing well-defined three-dimensional shape and rich functionality of the molecular surface. Molecules like dendrimers (1), cylindrically shaped brushes (2), and monodendron-jacketed polymers (3) are of particular interest in nanotechnology. These molecules have exceptional film-forming properties and can be utilized as molecular containers for drug delivery, construction units for molecular motors, polyfunctional catalysts, and templates for nanolithography. All of these applications take advantage of the well-defined morphology and synthetic versatility of such molecules, which enables control of their size, shape, interior structure, and surface functionality.
