摘要
合成了上缘特丁基脱去的杯 [4]芳烃 2 5 ,2 7-二丁氧基 - 2 6,2 8-二 (ω-十一碳烯氧基 )杯 [4]芳烃 ( p- H- C[4]B)及其相应的聚硅氧烷化高分子 ( PSO- p- H- C[4]B) ,以及上缘用 N,N-二乙基氨甲基取代的杯 [4]芳烃 5 ,1 1 ,1 7,2 3-四 ( N,N-二乙基氨甲基 ) - 2 5 ,2 6,2 7,2 8-四 (ω-十一碳烯氧基 )杯 [4]芳烃 ( p- DEAM- C[4]U) ,并首次将它们用作毛细管柱气相色谱固定液 ,涂制成色谱柱 ,考察了这些杯 [4]芳烃色谱柱的性能。结果表明 ,研制的杯
Two calixarene derivatives 25, 27, dibutoxy 26, 28 di ω undecenoxy calixarene ( p H CB) and 5, 11, 17, 23 tetra (N, N diethyl aminomethyl) 25, 26, 27, 28 tetra ( ω undecenoxy) calixarene ( p DEAM CU), and polysiloxane polymer of p H CB (PSO p H CB) were synthesized. Both p H CB and p DEAM CU were diluted with OV1701 and then were used as capillary gas chromatographic stationary phases while PSO p H CB was used directly. The p H CB OV1701 and PSO p H CB columns showed middle polarity while p DEAM CU column showed strong polarity. All of the three columns showed good selectivity to aromatic positional isomers.
