solubility in organic solvents such as acetone, dichloromethane, chloroform, pyridine, and ethyl acetate. Fluorescent quenching behavior was investigated using 1,4-benzoquinone and potassium iodide as a quencher. The photophysical (fluorescent quantum yields and lifetimes) and photochemical (single oxygen and photodegradation quantum yields) properties of these new phthalocyanines were examined in
在这项研究中,外围和非外围取代的 Zn(II) 酞菁配合物是由 7-hydroxy -3-( p -tolyl)coumarin和 7-hydroxy-3-( p -tosyl)coumarin 化合物合成的。使用元素分析、FT-IR、UV-Vis、荧光1对合成的新化合物进行表征HNMR 光谱和 MALDI-TOF 质谱。所有合成的酞菁配合物在丙酮、二氯甲烷、氯仿、吡啶和乙酸乙酯等有机溶剂中均表现出良好的溶解性。使用 1,4-苯醌和碘化钾作为猝灭剂研究了荧光猝灭行为。在二甲亚砜中检测了这些新酞菁的光物理(荧光量子产率和寿命)和光化学(单氧和光降解量子产率)特性。含有 7-hydroxy-3-( p -tolyl)coumarin的酞菁络合物比含有 7-hydroxy-3-( p -tolyl)coumarin 的酞菁络合物具有更高的单线态氧量子产率-甲苯磺酰)香豆素。香豆素外围结合的酞菁比
