organic compounds
The title compound, C14H15NO, is a key intermediate in the synthesis of the corresponding fluoran dye, which is used in thermal- or pressure-sensitive recording systems and light-resistant anthracene-type fluorescent colourants. The two aromatic rings are almost perpendicular to one another. The supramolecular aggregation is mainly due to the presence of π–π stacking interactions and intermolecular N—HO hydrogen bonds.
