1：Experimental Design and Method Selection:

High-temperature polycondensation reactions were used to synthesize the oligomers from TPS-core-based diamines and bis(4-formylphenyl)phenylamine, with p-toluenesulfonic acid as catalyst and anhydrous calcium sulfate as a water trap, under nitrogen atmosphere.

2：Sample Selection and Data Sources:

Silylated precursors and monomers were synthesized using bromo-lithium exchange and Suzuki-Miyaura cross-coupling reactions.

3：List of Experimental Equipment and Materials:

Equipment includes NMR spectrometer, FT-IR spectrometer, elemental analyzer, UV-Vis spectrometer, spectrofluorometer, TGA, DSC, GPC, and cyclic voltammetry analyzer. Materials include various chemicals such as 1,4-dibromobenzene, bis(4-formylphenyl)phenylamine, solvents like chloroform and THF, and catalysts.

4：Experimental Procedures and Operational Workflow:

Reactions were carried out at 60°C for

5：5 hours and then at 120°C for 20 hours, followed by precipitation, filtration, washing, and drying. Characterization involved FT-IR, NMR, elemental analysis, solubility tests, thermal analysis, molecular weight measurement, UV-Vis, photoluminescence, and cyclic voltammetry. Data Analysis Methods:

Data were analyzed using standard spectroscopic and electrochemical techniques, with band-gaps calculated from absorption edges and HOMO levels from cyclic voltammetry.
