Abstract
Two new kinds of calix[4]arene derivatives, 5,11,17,23-tetra- tert-butyl-25 ,27-bis(isopropylcarbamoyl-methoxy)-26,28-diundecenyloxy calix[4]arene (C[4 ]A) and 25,27-dibutoxy-5,11,17,23-tetra-tert-butyl-26,28-diundecenyloxy cal ix[4]arene (C[4]B), are prepared and then are polymerized by two different processes. Three calix[4]arene polysiloxane stationary phases for capillary gas chromatography are obtained. Their chromatographic characteristics, in cluding column efficiency, polarity, selectivity, glass-transition temperat ure and thermal stability are studied. Retention mechanisms are also discus sed.
