was used to measure the UV–vis spectra. Size exclusion chromatography
(Agilent GPC 1200) was applied to obtain the MW information on the
polymers relative to polystyrene references (eluent: ortho-dichlorobenzene). GIXS data were collected at beamline 3C in Pohang
Accelerator Laboratory in South Korea (incidence angle = 0.12–0.14°). Lcs from GIXS scatterings were estimated by Scherrer
equation where K = shape factor (0.9),
and Δq = the full width half-maximum of the peaks.
