In this paper we report evidence for an inclusion complex between carbon dioxide and p-t-butylcalixarene. The complex was studied with infrared spectroscopy,single-crystal X-ray diffraction, solid-state NMR, and thermogravimetric analysis.Results indicate that 70% of the p-t-butylcalixarene cavities could be occupiedby a CO2 molecule following exposure at 30 MPa and 40 °C.
