Hydrogen Bonded Molecular Capsule: Probing Role of Water Molecules for Capsule Formation in a Modified Cyclotricatechylene

Abstract

Two new pyridine moiety appended cavitands, CTC(Py)2(OH)2 and CTC(Py)3 were synthesized and characterized. The solid state structure of both cavitands were studied by single crystal X-ray diffraction. CTC(Py)2(OH)2 resulted in a hydrogen bonded dimeric molecular capsule, entrapping two molecules of DMSO and intervening water molecules those form hydrogen bondng to DMSO and CTC(Py)2(OH)2. When crystalized in absence of water, it forms a 2D polymer with hydrogen bonding of pyridine nitrogen and phenolic hydrogen atoms. CTC(Py)3 gives no such capsule.
