研究目的
Investigating the synthesis, characterization, and unique optical properties of five- and six-membered rings containing Si?B bonds.
研究成果
The synthesis and characterization of five- and six-membered Si?B rings were successfully achieved, revealing unique optical properties attributed to σ?π* transitions. DFT calculations supported the assignment of these transitions and provided insights into the electronic structure of the compounds.
研究不足
The study is limited to the synthesis and characterization of five- and six-membered Si?B rings. The stability of these compounds in air is limited, and their photophysical properties are not extensively explored.
