A series of discrete oligomers have been synthesized with the aim to study the behavior of these discrete blocks in block co-oligomers. Novel synthetic routes to oligo-dimethylsiloxanes are developed and combined with strategies to prepare a number of A-B and A-B-A block co-oligomers of different lengths, while there so-called mono-disperse analogues are prepared as well. “Where and when does it matter to use discrete block co-oligomers?” and “When is it useful to use just the mono-disperse analogue?” are just a few of the questions that will be discussed in the lecture. Where both blocks are amorphous the differences are small, however, discrete structures enhance crystallinity and then the differences become significantly. Intriguingly fast crystallization processes induced by phase separation are observed leading to fascinating adaptive materials. The assembly processes in thin films and in aqueous solutions will be presented with the aim to arrive at the ultimate perfection in nanotechnology.
