1：Experimental Design and Method Selection:

The authors proposed to control different content of mixed phases in DRTB-T and IDIC blends by additive and solvent vapor annealing (SVA). They first formed the largest extent amount of mixed phases by the additive cinene (2%) to inhibit the crystallization of DRTB-T and IDIC. And then, different amounts of mixed phases were achieved by further SVA for different times (from 0 to 50 s) to increase the content of pure DRTB-T and IDIC phases.

2：Sample Selection and Data Sources:

The samples used were DRTB-T and IDIC blends. The data sources included GIXD diffraction peak intensity, AFM images, PL of DRTB-T/IDIC, CV curves, and device performance data.

3：List of Experimental Equipment and Materials:

The equipment and materials included DRTB-T, IDIC, cinene additive, chlorobenzene (CB), 1,8-diiodooctane (DIO), diphenyl ethers (DPE), chloronaphthalene (CN), fluoronaphthalene (FN), methylnaphthalene (MeN), o-dimethoxybenzene (ODMB), 1,2,3-trichlorobenzene (TCB), and cinene.

4：Experimental Procedures and Operational Workflow:

The authors first inhibited the crystallization of DRTB-T and IDIC by the additive cinene (2%) to form a large number of mixed phases. Then, they used SVA for different times (from 0 to 50 s) to increase the content of pure DRTB-T and IDIC phases.

5：Data Analysis Methods:

The authors analyzed the data using GIXD diffraction peak intensity, AFM images, PL of DRTB-T/IDIC, CV curves, and device performance data.
