To gain deeper insights into the aggregated state we conducted a comprehensive dynamic light scattering (DLS) analyses in conjunction with absorption spectroscopy, atomic force microscopy (AFM), and filtering experiments (see Figure and Supporting Information). In this way we were able to directly compare and relate the findings of these different techniques and arrive with a consistent picture. For DLS analysis of aggregated E isomeric PAT 1 (Figure ), benzene was chosen as single solvent since solvent mixtures are much more difficult to analyze with this method (Figure ).
