TEM reveals the formation of uniform cylindrical micelles which exceed lengths of 500 nm and exhibit a regular shape which stands in contrast to the shorter irregular worm-like aggregates obtained from self-assembly in water. The formation of rather stiff cylindrical micelles is a typical feature of CDSA and, thus, points to crystallization as driving force for selfassembly in ethanol. They cylinders possess narrowly distributed thicknesses between 6 and 14 nm with a statistical average of 10.1 ± 0.1 nm. Such a thickness points towards a folding of the PhNCSco-OX chains within the cores. Heating of the analogous sample for another 3 days results in a different morphology as apparent from a shift in the DLS trace from an average diameter of 170 to 770 nm. TEM reveals the fusion of the cylindrical micelles obtained after 1 day to platelet-like structures although these structures are less uniform than the cylindrical aggregates from before. Similar platelets can also be obtained by sonification of the bulk material followed by annealing although further investigation of ROCOP polymers in crystallisation driven self-assembly are required.
