1：Experimental Design and Method Selection:

The synthesis of semi-fluorinated p-terphenyls was achieved via Suzuki-Miyaura cross-coupling reaction. Thermal and optical properties were characterized using DSC, POM, XRD, UV-vis, and fluorescence spectroscopy.

2：Sample Selection and Data Sources:

p-Terphenyls with two or four fluorine atoms in the central ring were synthesized. Data were obtained from thermal and optical characterization techniques.

3：List of Experimental Equipment and Materials:

Instruments included a Jeol 300 MHz spectrometer for NMR, a Nicolet Magna spectrophotometer for FTIR, a PerkinElmer 2400 Series II CHNS/O Elemental Analyzer, a DuPont Instruments TGA 951, a Mettler FP94HT DSC, an Olympus POM, an Anton Paar SWAXS, a Shimadzu UV-2401PC spectrophotometer, and a Perkin Elmer LS-50B spectrofluorimeter.

4：Experimental Procedures and Operational Workflow:

Synthesis involved alkylation, formation of aryl boronic acids, and Suzuki-Miyaura cross-coupling. Characterization included thermal stability, phase transitions, optical textures, X-ray diffraction, UV-vis absorption, and fluorescence measurements.

5：Data Analysis Methods:

Data were analyzed to determine thermal transitions, molecular stacking configurations, absorption and emission characteristics, and quantum yields.
