【Abstract】 The infrared and Raman spectra of two p tert butylcalix[6] arenes are reported in this paper.The circular intramolecular hydrogen bonds of calix[6] arene Ⅰ( p tert butylcalix[6] arene) and the three centered hydrogen bonds of calix[6] areneⅡ(1,3,5 trimethylated calix[6] arene) were displayed in the infrared spectra.Moreover,the optional conformation of calix[6] arenes in the solid state which was called a pinched cone was determined with IR spectroscopy.Calix[6] arene Ⅰ and Ⅱ are all calix[6] arenes,however,the Raman spectra of calix[6] arene Ⅰ were very different from those of calix[6] arene Ⅱ,because the circular hydrogen bonds of calix[6] arene Ⅰ and the three centered hydrogen bonds of calix[6] arene Ⅱ appeared to have great effect on the molecular vibration.更多还原
