合成了被溴和碘等重原子取代的新型氮杂-BODIPY衍生物，并研究了它们的三线态和单线态氧生成效率。这些衍生物在近红外区域表现出吸收，具有高摩尔消光系数。用四个碘原子取代的染料显示出 Phi(T) = 0.78 和 Phi(O-1(2)) = 0.70 的产率，这是迄今为止获得的氮杂-BODIPY 衍生物的最高值。
Novel aza-BODIPY derivatives substituted with heavy atoms such as bromine and iodine were synthesized, and their triplet and singlet oxygen generation efficiencies have been investigated. These derivatives showed absorption in the NIR region with high molar extinction coefficients. The dye substituted with four iodine atoms showed yields of Phi(T) = 0.78 and Phi(O-1(2)) = 0.70, which are the highest values so far obtained for the aza-BODIPY derivatives.
