Molecular electronics has made considerable progress in recent decades. The construction of a stable "electrode-molecule-electrode" junction is critical for the study of molecular electronics, as the stability can promote the exploration of the electrical properties of individual molecules and enable the prolonged observation of physical and chemical phenomena at the single-molecule scale. However, dispersed discussions and conflated concepts hinder our understanding of molecular junction stability. In this review, we systematically discuss the stability of molecular junctions from both thermodynamic and kinetic perspectives, summarize key quantitative parameters and their interrelationships, and provide an overview of the influencing factors at the molecule-electrode interface, as well as the experimental and theoretical analysis methods. We anticipate that this review will contribute to a thorough understanding of the stability of molecular junctions and offer valuable insights for the design of molecular devices based on molecular junctions.
