摘　　要：This work reports the investigation of a new triptycene-derived oxacalixarene(TDOC)as the stationary phase for gas chromatography(GC)with high-resolution performance for a wide range of analytes and isomers.The TDOC scaffold is composed of triptycene and 1,8-naphthyridine moieties,inherently differing from the conventional calixarenes in structures and properties.As a result,the TDOC column exhibited outstanding column efficiency of 5679 plates/m by n-dodecane at 120℃.It showed advantageous performance for separations of the mixtures with various analytes and achieved high resolution of diverse isomers(skeletal,positional and cis-/trans-isomers)from apolar to polar nature.Moreover,the TDOC column exhibited high thermal stability up to 310℃.To date,the TDOC-based materials have not been reported in chromatography.This work demonstrates the good potential of the triptycene-derived heterocalixarenes as a new class of stationary phases for chromatographic analyses.
