Assembling process of PPV₁₂-b-P2VP _n in 2-PrOH solution. a, b The morphology factor R_g/R_h (ρ) of PPV₁₂-b-P2VP₂₂ in 0.05 mg ml⁻¹ 2-PrOH solution after aging for 2 days was calculated to be 1.36 by DLS and SLS. The root mean square radius of gyration (R_g) is calculated by measuring SLS results of PPV₁₂-b-P2VP₂₂ in 0.05 mg ml⁻¹ 2-PrOH solution at different angles and determined through Berry Plot a, and the hydrodynamic radius (R_h) was calculated by measuring D_hθ of the sample solution at different angles by DLS and extrapolating the value b. Detailed calculation process was described in Methods part. c Plots of the solution temperature versus morphology factor R_g/R_h (ρ) of formed PPV₁₂-b-P2VP₂₂ aggregations in 0.05 mg ml⁻¹ 2-PrOH solution. d 2D GIWAXS pattern and e GIWAXS profiles along the in-plane direction of platelet 2-D square micelles obtained from PPV₁₂-b-P2VP₂₂ in 0.05 mg ml⁻¹ 2-PrOH solution. The data cut in the plot was caused by the gap of the detector. f Molecular dynamics simulations of the assembly states in platelet 2-D square micelles of PPV₁₂-b-P2VP₁₂. The left one is the final self-assembled structure after simulation in isopropanol, and the solvent molecules are not shown for clarity. The right one is a local display of two neighborhood molecules in assembled structure. g Illustration of growing process of platelet 2-D square micelles of PPV₁₂-b-P2VP _n
