1：Experimental Design and Method Selection:

The study uses additive DISC patterning, which involves sequential evaporation of dopants through a shadow mask onto polymer films, followed by development in solvents to dissolve undoped regions. Confocal fluorescence microscopy and atomic force microscopy (AFM) are employed to analyze dopant distribution and pattern fidelity.

2：Sample Selection and Data Sources:

P3HT films of specified thicknesses (e.g., 50 nm) are spin-coated from different solvents (chloroform, chlorobenzene, ortho-dichlorobenzene) to vary crystallinity. Dopants like F4TCNQ and F4MCTCNQ are used. Samples are characterized using optical and AFM techniques.

3：List of Experimental Equipment and Materials:

Equipment includes spin coater, thermal evaporator (MBraun), confocal microscope (Zeiss LSM 700), AFM (Digital Instruments Multimode), UV/vis spectrometer (Perkin Elmer 700), fluorescence spectrometer (Varian Eclipse). Materials include P3HT, F4TCNQ, solvents (chloroform, chlorobenzene, ortho-dichlorobenzene), glass substrates, TEM grids.

4：Experimental Procedures and Operational Workflow:

Films are spin-coated, dopants evaporated through a shadow mask, samples developed in solvents, and characterized using microscopy and spectroscopy. All steps are performed in a nitrogen glovebox to prevent oxidation.

5：Data Analysis Methods:

Fluorescence intensity is calibrated to estimate dopant concentration. AFM cross-sections are analyzed for feature dimensions and derivatives to quantify pattern sharpness. Statistical analysis is applied to multiple samples.
