Oligomeric and Polymeric Catenanes

摘要: Mechanically interlocked molecular level architectures ranging from naturally occurring DNA catenanes to the random entrapment of macrocycles within cross linked polymers and poly[2]catenane macromolecules are beginning capture imagination scientists all disciplines. The recent improvements in methods for [2]catenane synthesis mean that structures now becoming increasingly available as building blocks cores novel macromolecular materials. As yet few examples exist high mass ‘material like’ polycatenane structures, much work date has been on a steep learning curve which suggests exciting times lie ahead developing Many new mechanically polymer systems will undoubtedly be developed over next years. Despite wealth suggestions concerning possible properties such may possess, there is little experimental evidence either support or reject whatever claims made. characterisation structure-property relationships these materials begin unfold and, turn, used develop further synthetic programmes, answers questions resolved effects mechanical linkages bulk surface understood.
