具有纳米级内部的形状持久性大环允许在环的限定位置处附接（官能）侧基。这些侧基可以具有相对于分子主链的固定取向，或者它们可以根据外部刺激来调整它们的取向。化合物的性质和应用在很大程度上取决于这些侧基的取向。具有环内或适应性长烷基的大环显示了一种新的分散液晶设计原理。具有环外（低聚）烷基的大环可用于纳米范围内的表面图案化，并且具有环外低聚苯乙烯基的环能够聚集成超分子中空聚合物刷。
Shape-persistent macrocycles with an interior in the nanometer regime allow the attachment of (functional) side groups at defined positions at the ring. These side groups can have either a fixed orientation relative to the molecular backbone or they can adapt their orientation according to an external stimulus. The properties and applications of the compounds depend strongly on the orientation of these side groups. Macrocycles with intraannular or adaptable long alkyl groups display a new design principle for discotic liquid crystals. Macrocycles with extraannular (oligo)alkyl groups can be used for surface patterning in the nanometer regime and rings with extraannular oligostyryl groups are able to aggregate to supramolecular hollow polymer brushes.
