1：Experimental Design and Method Selection

The study involved the design and synthesis of red-emitting TADF polymers using PFDMPE as the backbone to increase triplet energy and prevent unwanted triplet energy back-transfer. The methodology included the synthesis of polymers with varying ratios of a red TADF emitter (ROC8) attached to the PFDMPE backbone.

2：Sample Selection and Data Sources

Samples were synthesized with varying feed ratios of ROC8 to PFDMPE, and their photophysical and electrochemical properties were characterized.

3：List of Experimental Equipment and Materials

Equipment included a Bruker Avance 400 NMR spectrometer, PerkinElmer-TGA 7 and PerkinElmer-DSC7 systems for thermal analysis, and a PerkinElmer Lambda 35 UV?vis spectrometer and PerkinElmer LS 50B spectro?uorometer for optical measurements. Materials included 2-(N-(4-octyloxyphenyl)diphenylamino)-4′-anthraquinone (ROC8) and poly(?uorene-co-3,3′-dimethyl diphenyl ether) (PFDMPE).

4：Experimental Procedures and Operational Workflow

The synthesis involved the preparation of ROC8 and its attachment to the PFDMPE backbone via a series of chemical reactions, including Suzuki polymerization. The polymers were then characterized for their photophysical and electrochemical properties, and their performance in PLEDs was evaluated.

5：Data Analysis Methods

Data analysis included the measurement of photoluminescence quantum yields, transient PL spectra, and electroluminescence performance in PLED devices.
