Pd. Beer et al., SYNTHESIS AND X-RAY CRYSTAL-STRUCTURE OF A NEW REDOX-ACTIVE CALIX[5]ARENE CONTAINING A TOTALLY INCLUDED ETHANOL MOLECULE, Journal of the Chemical Society, Chemical Communications, (18), 1995, pp. 1851-1852
A novel p-tert-butylcalix[5]arene trisferrocenoyl ester molecule L has
been prepared; the X-ray crystal structure of the ethanol complex of
L reveals the guest molecule bound deep in the cavity of the calix[5]a
rene.
