Synthesis of Crown Ethers Based on 9,9-Bis-(4-hydroxyphenyl)fluorene and Structural Determination by X-Ray Single Crystallography

摘要

We report the synthesis and characterization of [38],[57],[76] and [48]-membered crown ethers including bis-(hydroxyphenyl)fluorene in the macroring. Four crown ethers 1-4 are characterized by MALDI-mass spectral data and 1H-NMR data. Also, structural determination of [38]-membered crown ether 1 has been performed by X-ray crystallography.
