This lecture will highlight the relevance of sequence-controlled polymers for preparing monocyclic and polycyclic topologies. Indeed, sequence-controlled copolymerizations allow precise chain-positioning of functional monomers, which can be utilized after polymerization for cyclization (i.e. intramolecular covalent chemistry in dilute conditions). For instance, the controlled radical copolymerization of styrene with functional N-substituted maleimides enables preparation of a variety of linear precursors. This sequence-controlled synthetic platform was, for example, used for the synthesis of monocyclic (rings, tadpoles, alpha structures) and bicyclic topologies (eight-shaped macromolecules). The pros and cons of this novel approach will be discussed in the present lecture.
