Novel red‐emissive carbon‐dots (C‐dots) with broad absorption in the region from 400 to 750 nm are prepared from polythiophene phenylpropionic acid. Upon near infrared laser irradiation, the red‐emissive C‐dots show strong photoacoustic response and high photothermal conversion efficiency ( η ≈ 38.5%). These unique properties enable the C‐dots to act as multifunctional fluorescent, photoacoustic, and thermal theranostics for simultaneous diagnosis and therapy of cancer.
