Abstract Conformational changes in macromolecules significantly affect their functions and assembly into high‐level structures. Despite advances theoretical experimental studies, investigations the intrinsic conformational variations dynamic motions of single remain challenging. Here, liquid‐phase transmission electron microscopy enables real‐time tracking single‐chain polymers. Imaging linear polymers, synthetically dendronized with conjugated aromatic groups, organic solvent confined within graphene liquid cells, directly exhibits chain‐resolved dynamics individual semiflexible These analyses reveal that transitions polymer originate from degree intrachain interactions. In situ observations also show such are affected by environmental factors, including surfaces interfaces.
