摘　　要：This work presents a novel strategy for engineering a GC stationary phase with high selectivity,inertness and thermal stability by introducing the 3Dπ-rich TP moieties to the terminals of a polar chain polymer.Herein,we provide the first example,i.e.,a new TP-terminated polycaprolactone polymer(TPP)as the stationary phase for GC analyses.As demonstrated,the TPP column achieved distinctly improved inertness to fatty acids and aldehydes,and dramatically enhanced thermal stability(about 100°C higher)over the PCL column.Also,the TPP column exhibited high resolving capability towards the positional isomers of phenols,anilines and alkylated/halobenzenes and showed good potential in detecting minor impurities in chemical products.Importantly,the proposed strategy is facile,feasible and generally applicable to analogous polymers.
