emission and fluorogenicity. However, the applications of heteroatom-substituted rhodamines have been hindered by difficult synthetic routes. Herein, we explored the condensation strategy of diaryl etheranalogues and o-tolualdehyde to synthesize various heteroatom-substituted rhodamines. We found that the electron property and steric effect in the rhodamine 10th position determined the synthetic yield.

Photothermaltherapy (PTT) is a cutting-edge cancer treatment that can kill cancer cells in hypoxic environments without relying on oxygen. Seeking of the ideal photothermal agents with a high absorption coefficient in the near-infrared region, and a high excellent photothermal conversion efficiency is of great significance. Sulfone-Rhodanmine dye has showed an impressive absorption wavelength over
