In the crystalline state of the title solvate, C18H13NO3·C4H8O, hydrogen-bonding interactions between hydroxyl groups on a phenoxazine backbone and the tetrahydrofuran solvent are observed that suggest the ability for this compound to act as a chelating ligand. The O...O donor–acceptor distances for this hydrogen bonding are 2.7729 (15) and 2.7447 (15) Å. The three-ring backbone of the phenoxazine bends out of planarity by 18.92 (3)°, as computed using mean planes that encompass each half of the three-ring structure, with the central N and O atoms forming the line of flexion. In the crystal, a π–π stacking arrangement exists between inversion-related molecules, with a centroid-to-centroid distance of 3.6355 (11) Å. In the disordered tetrahydrofuran solvate, all atoms except oxygen were modeled over two positions, with occupancies of 0.511 (8) and 0.489 (8).

Small-molecule organic compounds have emerged as attractive candidates for energy storage in lithium-ion batteries due to their sustainability and modularity. To develop generalizable design principles for organic electrode materials (OEMs), we investigated the correlation between electrochemical performance and addition of functional groups that promote synergistic hydrogen bonding and π-π stacking using a series of quinone-fused aza-phenazines (QAPs) with different hydrogen bonding donor/acceptor arrays. The QAP containing the most hydrogen bonding groups (<b>3</b>) exhibits the best performance with discharge capacities of 145 mAh g<sup>-1</sup> at 2C with 82% capacity retention over 1000 cycles. The performance of <b>3</b> is attributed to the strategically incorporated -OH and -NH<sub>2</sub> groups, which facilitate strong intermolecular interactions and a tightly packed 2D structure. The intermolecular interaction strength was evaluated using variable temperature 1D <sup>1</sup>H NMR and 2D <sup>1</sup>H-<sup>1</sup>H NOESY, offering a new strategy to help understand and predict the performance of OEMs with hydrogen bonding motifs.
