Two new azamacrocycle-based stationary phases for high-performance liquid chromatography: Preparation and comparative evaluation

► Two azamacrocycle-based HPLC stationary phases were prepared and evaluated. ► The new phases show satisfactory chromatographic performance toward solutes. ► CycHe3Ph3[30]aneN6CPS is superior in separation of aromatic amines and PAHs. ► The larger azamacrocycle facilitates shape and planarity recognition of isomers. ► The phases show multiple-interaction mechanism, which is testified by LSER model.
