摘要: Abstract This work presents the investigation of permethyl pillar[5]arene (MP5) as stationary phase for capillary gas chromatographic (GC) separations. The MP5 column fabricated by sol-gel coating method exhibited weak polarity and high efficiency over 4200 plates/m n -dodecane, -octanol naphthalene. Particularly, displays unique retention dibromoalkanes, which was found to be closely related with linker length, shows resolving capability a wide range positional structural isomers, including alkylbenzenes, chlorobenzenes chloronitrobenzenes, naphthalene derivatives, phenols anilines. Moreover, showed good thermal stability repeatability reproducibility relative standard deviation in 0.02–0.04% intra-day, 0.32–0.46% inter-day 1.5–3.4% between-column, respectively. demonstrates an promising future pillar[n]arenes new type
