Four kinds of macrocyclic polyethers containing isobutenyl group and aromat
ic rings were synthesized. X-ray analyses of crystal structure revealed sig
nificant differences in conformation among the compounds studied, in spite
of their similarity in chemical formula. One compound was found to capture
a benzene molecule in crystalline phase, while the others did not. (C) 1999
