A NIR photosensitizer Cy5.5-Br was designed and synthesized based on a cyanine derivate (Cy5.5-H), which presented extraordinary super heavy atom effect (SHAE) and structure-inherent targeting (SIT) to tumors. Moreover, Cy5.5-Br has a satisfactory triplet quantum yield, an unusual long-lived triplet state and excellent photostability upon hot-band excitation, which makes it possible to realize effective
基于花青衍生物(Cy5.5-H)设计并合成了一种近红外光敏剂Cy5.5-Br,该光敏剂对肿瘤具有非凡的超重原子效应(SHAE)和结构固有靶向(SIT)。此外,Cy5.5-Br具有令人满意的三重态量子产率、不寻常的长寿命三重态和优异的热带激发光稳定性,这使得在生物安全光密度下实现有效的 PDT 成为可能。
