The changes in the SCO properties are more pronounced for the fully annealed samples (orange curve in Figure ). Here, we can show that the enlargement of the particles and the morphological changes into worm-like structures alters the SCO to be more complete, e.g. with HS fractions at 50 K changing from γHS = 0. graphically in Figure , where the MT values at 50 K are plotted vs. the annealing temperature for selected samples. Apparently, for the as-synthesized samples the CP chain length in the NPs is independent from the particle size, leading similar γHS values both, at room temperature and at 50 K. This indicates that for the assynthesized samples the CP chain length and by this γHS only depends on the synthesis cycles, which were not varied here. Upon confined recrystallization of the CP within the polymer shell, the chain lengths increase and now the γHS values at 50 K correlate with the particle size and loading. T-PXRD pattern were measured for the samples 1-5e to confirm the recrystallization of the CP. The relative intensity of the newly detected reflexes after thermal annealing increased continuously from sample 1e to 5e (Figure ), in line with the increase of the particle size.
