Abstract: Dibenzoacridine derivatives can be used as coating materials for microsensor. They have also been widely used as improved receptors in coordination and superamolecule chemistry. In this study, NMR techniques, including ¹H NMR, ¹³C NMR, DEPT, HSQC, HMBC, and mass spectrometry (MS) were used in combination to elucidate the structure of a dibenzoacridine derivative 7-(4-methoxy-phenyl)-5,6,8,9-tetrahydro-dibenzo [c, h]acridine. The ¹H and ¹³C chemical shifts of the compound were assigned.

Key words: NMR, assignment, 2D NMR, dibenzoacridine, spectroscopic analysis
