Analogues of Texas red incorporating the heavy chalcogens S, Se, and Te atoms in the xanthylium core were prepared from the addition of aryl Grignard reagents to appropriate chalcogenoxanthone precursors. The xanthones were prepared via directed metalation of amide precursors, addition of dichalcogenide electrophiles, and electrophilic cyclization of the resulting chalcogenides with phosphorus oxychloride and triethylamine. The Texas red analogues incorporate two fused julolidine rings containing the rhodamine nitrogen atoms. Analogues containing two “half-julolidine” groups (a trimethyltetrahydroquinoline) and one julolidine and one “half-julolidine” were also prepared. The photophysics of the Texas red analogues were examined. The S-analogues were highly fluorescent, the Se-analogues generated single oxygen (1O2) efficiently upon irradiation, and the Te-analogues were easily oxidized to rhodamines with the telluroxide oxidation state. The tellurorhodamine telluroxides absorb at wavelengths ≥690 nm and emit with fluorescence maxima >720 nm. A mesityl-substituted tellurorhodamine derivative localized in the mitochondria of Colo-26 cells (a murine colon carcinoma cell line) and was oxidized in vitro to the fluorescent telluroxide.

In the anion of the title hydrated salt, C2H10N2 2+·C21H13N3O8S2?·2H2O, the planes of the phenyl rings and the benzene ring of the 5-nitro-2-oxidobenzenesulfonate group are inclined to one another by 44.42?(11), 56.87?(11) and 77.70?(12)°. In the crystal, the anions are linked to the cations and the water molecules by N?H?O and O?H?O hydrogen bonds, forming a three-dimensional network. Furthermore, there are face-to-face π-π stacking interactions between the centroids of one phenyl ring and the benzene ring of the 5-nitro-2-oxidobenzenesulfonate group [centroid-centroid distance = 3.8382?(13)?a and slippage = 1.841?a]. A Hirshfeld surface analysis was conducted to verify the contributions of the different intermolecular interactions.

In the title molecule, C17H17NO4, the dihedral angle between the two aromatic rings is 42.47?(7)°. The nitro group is twisted by 7.44?(11)° out of the plane of the ring to which it is attached. The methoxy and ethoxy group O atoms deviate significantly from the phenyl ring [by 0.0108?(11) and 0.0449?(11)?a, respectively]. The crystal structure is stabilized by C?H?π interactions.
