研究目的
Investigating the synthesis and characterization of near-infrared (NIR)-absorbing/emitting Thiele’s hydrocarbon derivatives and their unique properties.
研究成果
BTAQs represent a new class of organic molecules with potential applications in technologies utilizing NIR light, due to their stable NIR absorption/emission and two-step electrochromism without biradical character.
研究不足
The synthesis yields of some BTAQs were relatively low, and the stability under various conditions was not extensively tested.
1：Experimental Design and Method Selection:
Synthesis of BTAQs using concentrated sulfuric acid as a solvent and optimization of reaction conditions.
2：Sample Selection and Data Sources:
Use of commercially available 2-(4-dialkylamino-2-hydroxybenzoyl)benzoic acid and 1,4-dimethoxybenzene.
3：List of Experimental Equipment and Materials:
Concentrated sulfuric acid, MALDI-TOF-MS for detection, NMR spectroscopy, and high-resolution mass spectroscopy for characterization.
4：Experimental Procedures and Operational Workflow:
One-step synthesis from starting materials, characterization by NMR and mass spectroscopy, X-ray crystallographic analysis.
5：Data Analysis Methods:
DFT and TDDFT calculations for understanding the properties of BTAQs.
