Efficient Multicomponent Active Template Synthesis of.
In nature, catenanes are involved in the action of topoisomerases forming knotting catenanes that regulate replication and genetic expression (43). The synthesis of DNA catenanes for applications in DNA nanotechnology often involves use of multiple ssDNA templates that are designed to contain regions of DNA complementarity.
However, there has been no established way to synthesize catenanes in which Lk is controlled to a predetermined value. This paper reports a new methodology to selectively synthesize Lk 1 catenanes composed of single-stranded DNA rings, in which these rings can most freely rotate each other due to minimal inter-ring interactions.
There are two primary approaches to the organic synthesis of catenanes. The first is to simply perform a ring-closing reaction with the hope that some of the rings will form around other rings giving the desired catenane product.
About this book. This journey through the fascinating world of molecular topology focuses on catenanes, rotaxanes and knots, their synthesis, properties, and applications and the theory of interlocking and interpenetrating molecules.

Synthesis There are two primary approaches to the organic synthesis of catenanes. The first is to simply perform a ring-closing reaction with the hope that some of the rings will form around other rings giving the desired catenane product.
Synthesising evidence Key words: balance, integrating, synthesising When you are writing your essay, you will be developing your point of view (thesis) through each body paragraph you write. Everything you have to say must be supported with evidence from a range of sources.
Synthetic methods for the production of mechanically interlocked molecules, in particular catenanes and rotaxanes, have improved immeasurably since the ground-breaking first reports of their synthesis in low yield using statistical methods in the 1960s.
Rotaxane- and catenane-based molecular machines and motors. catenanes are promising systems for the construction of artificial molecular machines. The design, synthesis and investigation of chemical systems able to function as molecular machines and motors is of interest not only for basic research, but also for the growth of.
