Comparing the behaviour for different chain lengths at the same φ V N 1/2 (ESI Fig. ), a slightly lower average overlap fraction ⟨N pair ⟩/N was observed with increasing chain length, which may be attributed to faster folding of the longer single chains. This behaviour will be discussed in more detail in Section 3.3. It should also be noted that we have assumed ideal chains in using φ V N 1/2 to scale the polymer concentration, from which the behaviour of our CG model in poor solvents is likely to deviate.
