Controlling ion recognition in reactive host-guest systems
Sometimes a molecule can only undergo a particular chemical reaction if it forms a so-called host-guest complex together with another molecule — the two molecules are then bound together not by covalent bonds but by intermolecular forces. What happens is…

Forward or backward? New pathways for protons in water or methanol
A collaborative ultrafast spectroscopy and ab initio molecular dynamics simulations study shows that proton vacancies in the form of hydroxide/methoxide ions are as relevant for proton transfer between acids and bases as hydrated excess protons (H3O+, H5O2+), thus pointing for…
A simple way to control swarming molecular machines
The swarming behavior of about 100 million molecular machines can be controlled by applying simple mechanical stimuli such as extension and contraction. This method could lead to the development of new swarming molecular machines and small energy-saving devices. The swarming…
Accidental discovery of strong and unbreakable molecular switch
