The in-situ study of the electrochemical behavior of Fc12-Br/d-MO was performed on the ZOOM SANS beamline (STFC ISIS Pulsed Neutron Source, Oxfordshire, UK). The beamline was run in time-of-flight mode with incident wavelengths from 1.75 Å to 16.5 Å. The sample detector distance (SDD) was 4 m, with beam size of 8 mm x 6mm and a typical q-range from 0.004 Å -1 to 0.7 Å -1 . Exposure time was set as 30 min each frame. For in-situ data, the data was sliced every 15 min to resolve any time-evolving features. The scattering intensity was normalized to the absolute scale calibrating against the intensity of a polystyrene standard. Data reduction was made using Mantid Project. 52
