Supramolecular Polymers, Second Edition
For example, the PC containing 10% (w/w) catenane was Mn — 15.9 x 103, PDI
= 2.5. Solid-state properties of the catenane copolymer were determined using
DSC and dynamic mechanical analysis (DMA) and were compared with pure PC.
4.2.2 Poly[n]catenane Poly[n]catenane is a polymer that is composed only of
cyclic components. O1igo[n]catenanes were successfully prepared by a stepwise
manner. Stod- dart has approached some oligocatenanes synthesized on the
basis ...

consisted of both crystallizable (pure bisphenol-A PC) and uncrystallizable
segments (which were composed mainly of catenane subunits), and that
catenane ...

Organic Synthesis: The Science Behind the Art
Further developments in this field led to the elaboration of an alternative
approach that envisaged the creation of temporary bridges which forcefully held
together the parts of the future catenane or rotaxane. Quite a number of catenane
and ...

Core Concepts in Supramolecular Chemistry and Nanochemistry
The term 'catenane' is derived from the latin word catena, meaning chain. Unlike
rotaxanes, catenanes represent examples of true topologically connected
species. Once joined, the rings cannot be separated, no matter how they are
distorted, ...
