研究目的
Demonstrate the synthesis of a model system for porous nanographenes to study their chemical properties indirectly.
研究成果
The iterative process developed by the authors allowed for the expedient synthesis of the target molecule in good yield, enabling analysis by X-ray crystallography and revealing a 'wizard-hat shaped' molecule.
研究不足
The formation of large polycyclic aromatic hydrocarbons can be low yielding, but the iterative process developed by the authors improved the yield.
The methodology involves the deprotection of an alkoxyphenol with Br3B, followed by triflation and subsequent Suzuki–Miyaura coupling, allowing for the expedient synthesis of the target molecule in good yield. Elaboration to form the final product enabled analysis by X-ray crystallography.
