研究目的
Investigating the effect of introducing two bulky aromatic amine groups at 1,8-positions of a carbazole on the TADF characteristics and OLED performance.
研究成果
The introduction of two aromatic amine groups at 1,8-positions of a carbazole creates efficient TADF emitters with high PLQYs and excellent OLED performance, demonstrating the potential of this molecular design strategy for developing high-performance solution-processed OLEDs.
研究不足
The study focuses on the specific molecular design of carbazole-based emitters and their application in solution-processed OLEDs, which may limit the generalizability to other types of emitters or fabrication methods.
1：Experimental Design and Method Selection:
The study involved the synthesis of two emitters, PAPTC and BPAPTC, through Suzuki cross-coupling reaction, characterized by X-ray diffraction and photophysical measurements.
2：Sample Selection and Data Sources:
The emitters were studied in toluene solution and doped films.
3：List of Experimental Equipment and Materials:
X-ray diffraction for structural analysis, photoluminescence quantum yield measurements, transient PL decay analysis.
4：Experimental Procedures and Operational Workflow:
Synthesis of emitters, fabrication of OLED devices by solution-processing, measurement of photophysical properties and device performance.
5：Data Analysis Methods:
Time-dependent density functional theory (TD-DFT) calculations for charge distribution and separation analysis.
