Abstract Novel magnesium(II) porphyrazine with peripheral methyl(3,5-dibromophenylmethyl)amine groups was synthesized in a multi-step procedure starting from commercially available diaminomaleonitrile. All intermediates and the final macrocycle were characterized using UV–Vis, FT-IR, MS and various NMR techniques. The absorption and emission properties of the macrocycle were evaluated in N,N-dimethylformamide, dimethyl sulfoxide, and dichloromethane. The potential photosensitizing activity was evaluated by assessing the ability of the macrocycle to generate singlet oxygen in dimethyl sulfoxide and N,N-dimethylformamide.

具有外围甲基（3,5-二溴苯基甲基）氨基的四氮杂镁 - 合成和光学性质

摘要 以市售二氨基马来腈为原料，采用多步法合成了具有外围甲基（3,5-二溴苯基甲基）胺基团的新型镁（II）四氮杂卟啉。使用 UV-Vis、FT-IR、MS 和各种 NMR 技术对所有中间体和最终大环进行表征。在 N,N-二甲基甲酰胺、二甲亚砜和二氯甲烷中评估大环的吸收和发射特性。通过评估大环在二甲亚砜和 N,N-二甲基甲酰胺中产生单线态氧的能力来评估潜在的光敏活性。
