Redox‐active guanidines are versatile reagents in redox and proton‐coupled electron‐transfer (PCET) reactions. Recently, they were integrated as sacrificial electron donors for the prohibition of metal oxidation in perovskite materials. Herein we report the synthesis and characterization of several new redox‐active guanidines with aromatic (benzene, naphthalene or anthraquinone) cores. Two of these
氧化还原活性胍是氧化还原和质子偶联电子转移(PCET)反应中的多功能试剂。最近,它们被集成为牺牲电子供体,用于禁止钙钛矿材料中的金属氧化。在这里,我们报告了几种具有芳香族(苯,萘或蒽醌)核的新型氧化还原活性胍的合成和表征。然后将其中两种化合物整合到碘化铅材料中。对所得材料的结构,热稳定性和光学带隙进行了评估。
