Abstract: A mono-adenine-functionalized pillar[5]arene and a guest including uracil were prepared. They formed a novel four-unit [c2]daisy chain both in the solid state and in a chloroform solution. As far as we know, this [c2]daisy chain is the first one without a covalently bound linear thread. This unique assembly behavior is mainly induced by hydrogen-bond interactions between A and U in the A-U base pairs.
