Abstract

Herein we report an efficient adsorptive separation approach for monobromotoluene isomers using nonporous adaptive crystals of perbromoethylated pillar[5]arene (BrP5). The purity of separated m-bromotoluene from an equal volume mixture of m-bromotoluene and o-bromotoluene reaches 96.6% in one cycle and the adsorbent BrP5 can be reused without losing separation performance.
