Investigation of the controlled release of tertiaryalcoholsfrom the surface of dendrimers and “stylomers” as polymer model systems (see scheme) showed that the polarity of the conjugates and structural modifications in close proximity to the release unit have a stronger influence on the rates of hydrolysis than the size (generation) or shape (linear or spherical) of the macromolecules.

Multi-bridged cryptands were formed in one step by condensation of two moles of a tetraaldehyde with four moles of a triamine. This is the first example of a tetrapode capping reaction.

A general concept for a versatile convergent synthesis of polynitrile and/or polyamine dendrimers has been developed by applying Vogtle's procedure in combination with the tandemhydroformylation/reductiveamination sequence, known as hydroaminomethylation. In this approach, first Vogtle's procedure is used to generate the desired dendron, which can then be attached to different types of polyfunctionalized
