Self‐catalysis is defined as catalysis by a product of a chemical reaction, that causes a significant increase in reaction rate in terms of the progress of the reaction. When a self‐catalytic reaction is involved in a reversible nonequilibrium‐to‐equilibrium chemical reaction, notable kinetic phenomena appear including sigmoidal kinetics, the seeding effect, thermal hysteresis, and chiral symmetry breaking. The nature of self‐catalytic reactions is characterized by microscopic mechanisms involving pathways of molecular structural changes and by macroscopic mechanisms involving molecular flux. Reversible self‐catalytic reactions, which exhibit notably high sensitivity to environmental changes, are also observed. In this Review, reversible self‐catalytic reactions of helicene oligomer foldamers during formation of homo‐ and hetero‐double‐helices are discussed, which exhibit the properties outlined above.

涉及Helicene齐聚物Foldamers自催化反应的合成化学体系。

自催化是指由化学反应产物引起的催化，根据反应的进行，反应速率显着增加。当自催化反应参与可逆的非平衡-平衡化学反应时，会出现明显的动力学现象，包括乙状动力学，晶种效应，热滞后和手性对称性断裂。自催化反应的性质以涉及分子结构变化途径的微观机制和涉及分子通量的宏观机制为特征。还观察到可逆的自催化反应，对环境变化表现出很高的敏感性。在这篇评论中，
