2,9-Diaryl-6,13-bs(triisopropylsilylethynyl)pentacene drivatives: synthesis and application in cancer sonodynamic therapy

Four 2,9-aryl substituted 6,13-bis(triisopropylsilylethynyl)pentacene derivatives were synthesized as sonosensitizers. Their extensive delocalized π-electron conjugation system facilitated the generation of reactive oxygen species (ROS) under ultrasound irradiation. Therapeutic results validate that the as-prepared compounds have significant advantages in sonodynamic therapy.
