  9‐Cyano‐10‐telluriumpyronin Derivatives as Red‐light‐activatable Raman Probes

  摘要：

  AbstractPhotoactivatable fluorescence probes can track the dynamics of specific cells or biomolecules with high spatiotemporal resolution, but their broad absorption and emission peaks limit the number of wavelength windows that can be employed simultaneously. In contrast, the narrower peak width of Raman signals offers more scope for simultaneous discrimination of multiple targets, and therefore a palette of photoactivatable Raman probes would enable more comprehensive investigation of biological phenomena. Herein we report 9‐cyano‐10‐telluriumpyronin (9CN‐TeP) derivatives as photoactivatable Raman probes whose stimulated Raman scattering (SRS) intensity is enhanced by photooxidation of the tellurium atom. Modification to increase the stability of the oxidation product led to a julolidine‐like derivative, 9CN‐diMeJTeP, which is photo‐oxidized at the tellurium atom by red light irradiation to afford a sufficiently stable oxidation product with strong electronic pre‐resonance, resulting in a bathochromic shift of the absorption spectrum and increased SRS intensity.

  Synthesis and Properties of Heavy Chalcogen Analogues of the Texas Reds and Related Rhodamines

  摘要：

  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 (O-1(2)) 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.
