Abstract
Photothermal therapy(PTT)is a cutting-edge cancer treatment that can kill cancer cells in hypoxic en-vironments 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 700 nm,but suffered from a stability issue.In this study,we synthesized five sulfone rhodamines and investigated the substitution effects on stability.S02R2 showed high stability and strong absorbance at 714 nm with an excellent photothermal conversion efficiency of 53.06％,making it suitable for accurate photoacoustic imaging-guided photothermal therapy in vivo.
