As an outcome, we obtained a complete picture of the rich dynamic and structural complexity/diversity of these assemblies. The results of our analysis show that supramolecular polymers of the same family (e.g., BTA) can appear both as straight nearly-perfect fibers or as more chaotic 1D filaments with a high population of defects, depending on the environment in which these are immersed. For example, the structure of the water-soluble BTA fiber studied herein is demonstrated to be a highly complex system, where the monomers in the assembly are present in multiple states that are in continuous exchange between them. Analyzing the interconversion probabilities between the different states, we could quantify the defect formation and repair pathways, and the associated probabilities (or rates), shedding new light into the dynamic nature of these complex supramolecular materials.
