Self-assembly of hyperbranched spheres

Abstract

A new type of building block with two coordinatively unsaturated palladium centres has been described that self-assembles in nitromethane solution and disassembles when acetonitrile is added. The resulting hyperbranched, organopalladium spheres have a remarkably narrow size distribution as was evidenced by light-scattering, AFM and TEM measurements. Variation of the structure of the building blocks showed the possibility to vary the size of the self-assembled spheres between 100 and 400 nm.
