Abstract

(Chemical equation presented) An unusually stable molecular capsule was formed by heating phenyleneurea-spanned resorcinarene cavitand with 4-methyl-N-p-tolylbenzamide. The molecular capsule behaved as a discrete molecular entity showing a cylindrical D4d structure and showed no guest exchange in toluene-d8 even at 100°C.
