Aromatic N-oxide templates open inclusion and dimeric capsular assemblies with methylresorcinarene

Abstract

C 2 -2-methylresorcinarene forms host-guest complexes with pyridine N-oxide and quinoline N-oxide. In solution the NMR studies support the 1:1 host-guest complexes while in the solid state, the single crystal X-ray diffraction studies reveal dimeric capsule-like assemblies with 2:3 and 2:2 host-guest stoichiometry.
