研究目的
To develop easily accessible red circularly polarized phosphorescent emitters for practical organic light-emitting diodes fabrication.
研究成果
The study successfully developed a new family of CPL-active platinum complexes based on the binaphthalene chiral platform, exhibiting aggregation-induced circularly polarized phosphorescence enhancement with high quantum yields and luminescence dissymmetry factors. The solution-processable CPOLEDs using these complexes as emitters showed good performance, paving the way for further development of high-performance CPL complexes for CPOLEDs.
研究不足
The study focuses on the development of red circularly polarized phosphorescent emitters, and the performance in terms of quantum yield and luminescence dissymmetry factor may need further optimization for broader applications.
1：Experimental Design and Method Selection:
The study involved the synthesis of axially chiral platinabinaphthalenes by directly incorporating platinum(II) into the π-conjugated backbone of commercially available enantiopure binaphthalene derivate.
2：Sample Selection and Data Sources:
Commercially available enantiopure (R)-/(S)-1,1'-bi-2-naphthol (BINOL) was used as the starting material.
3：List of Experimental Equipment and Materials:
The synthesis involved methylation, formylation, condensation, and metalation reactions.
4：Experimental Procedures and Operational Workflow:
The complexes were synthesized and characterized by UV-Vis absorption, photoluminescent spectra, and single-crystal X-ray diffraction.
5：Data Analysis Methods:
The photophysical properties were analyzed using UV-Vis absorption and photoluminescent spectra, and the chiroptical properties were investigated by circular dichroism (CD) and CPL spectroscopy.
