Abstract

Abstract: The visualization of self‐assembled structure and dynamics at the molecular level has become a powerful method to understand structure–function relationships of self‐assembly. Herein, we in situ real‐time imaged the dynamic process of benzyl‐naphthalimide dyes at the nanoscale and inspected their internal structure with minimum 2.8 nm localization accuracy through single‐molecule localization microscopy (SMLM) imaging. We monitored the growth process of three different assemblies in situ, which possessed highly heterogeneous dynamics with different shapes and growth rates. Furthermore, diverse growth rates were also found at different sites in the same assembly. These results highlight the application of super‐resolution microscopy techniques for real‐time visualization of internal assembled structure and dynamics in situ.
