摘　　要：The mixture of p-(methoxy)calix[n]arenes(n=6,7 or 8)was prepared in one step from p-methoxyphenol under basic conditions,and their fully methylated derivatives p-(dimethyloxy)calix[n]arenes(n=6,7 or 8)were also prepared and purified by column chromatography to indentify their structures.In this process,the single crystal of p-(dimethyloxy)calix[7]arene was obtained and its structure was confirmed.The proportion of p-(methoxy)calix[6]-,[7]-and[8]-arenes in the mixture obtained from the reaction was investigated under different reaction conditions,and p-(methoxy)calix[6]-and[8]-arenes could be separated from the mixture by solvent extraction.In addition,the host-guest interaction of p-(dimethyloxy)calix[6]arene with methyl-4,4′-bipyridinium hexafluorophosphate in organic solvents was investigated.
