ABSTRACT
Self-complementarity is a useful concept in supramolecular chemistry, molecular biology and polymeric systems. Two resorcinarene tetrabenzoxazines decorated with four oxalamide groups were synthesized and characterized. The oxalamide groups possessed self-complementary hydrogen bonding sites between the carbonyls and amide groups. The self-complementary nature of the oxalamide groups resulted in self-included dimeric assemblies. The hydrogen bonding interactions within the tetrabenzoxazines gave rise to the formation of dimers, which were confirmed by single-crystal X-ray diffractions analysis and supported by NMR spectroscopy and mass spectrometry. The self-included dimers were connected by numerous and strong intermolecular N-Hâ

π interactions, forming one-dimensional polymers, which were then further linked into three-dimensional networks.
