Therefore we have developed dynamic combinatorial chemistry, which is inspired by biological evolution and the mammalian immune system. We create complex equilibrating mixtures from which a template can gather around itself a successful host despite the complexity of the reaction mixture. This host can be selected, amplified, isolated and identified: we design the experiment, not the molecule. We can also exploit self-templating to create complex folded catenanes and knots. This provides the synthetic chemist with a selection approach to molecular recognition that complements the traditional design approach. It can change the way we think about synthesis and provide us with a way of exploring how complex systems respond to external stimuli. We will also discuss hydrogen-bonded supramolecularnanotubes: they self-assemble in solution from simple building blocks, and display rich host�guest chemistry, including the ability to dissolve C60 in organic solvents and to rearrange to give a different receptor in response to the presence of C70.
