used to characterize the compounds. The aggregation behaviors of 3–8 were also investigated at different concentrations in THF. Antioxidant test methods, α,α-diphenyl-β-picrylhydrazyl radical scavenging activity, metal chelating activity, and reducing power, were used to determine the antioxidant activities. 6 showed very good ferrous ion chelating activity of 81 ± 1%. 6, 5, 4, and 3 showed better
四α-或β-噻吩取代的金属和无金属酞菁 (Pcs) M[Pc(α-OCH2Thiopen)4] 和 M[Pc(β-OCH2Thiopen)4] (α-ThMet-MPc), (β -ThMet-MPc) [ThMet:甲氧基噻吩],M = Zn(II)、Co(II) 和 2H} 由相应的 3'-(噻吩-3-基甲氧基)邻苯二甲腈或 4'-(噻吩- 3-基甲氧基)邻苯二甲腈(ThMePN)。还介绍了一系列新 Pc 的结构表征、光谱和抗氧化特性。α-和 β-取代的 Pc 复合物都增加了在极性溶剂中的溶解度,如 THF、DMF 和 DMSO。FT-IR、1H-NMR、13C-NMR、UV-vis、MALDI-TOF/MS 光谱和元素分析数据用于表征化合物。还在不同浓度的 THF 中研究了 3-8 的聚集行为。抗氧化试验方法,α,α-二苯基-β-苦基肼自由基清除活性、金属螯合活性和还原能力用于测定抗氧化活性。6
