a

Domain spacing, d calculated from the principal scattering peak, q*: d = 2π/q*.

b

Observed Bragg reflections, missing peaks in ( ).

c

Proposed phase morphology based on SAXS data.

d

Expected phase state based on theoretical phase diagram from Matsen for linear ABA-triblock copolymers and literature SBCs of similar N and composition. LAM = lamellar, HEX = hexagonally packed cylinders, S = closed-packed spheres and DG = double gyroid.90,95–97
