Homogeneous catalysts with a mechanical (Machine-like) action

Journal Article


Abstract


  • Chemical reactions may be controlled by either: 1)the minimum threshold energy that must be overcome during collisions between reactant molecules/atoms (the activation energy, E-a) or: 2)the rate at which reactant collisions occur (the collision frequency, A)-for reactions with low E-a. Reactions of type 2 are governed by the physical, mechanical interaction of the reactants. Such mechanical processes are unusual, but not unknown in molecular catalysts. In this work we examine the machine-like nature of the action in various abiological mechanical catalysts and consider the implications for mimicry of biological catalysts.
