dicyanomethylene-bridged acridophosphine scaffold were synthesized and their reversible reduction potentials were efficiently tuned through derivatization of the phosphorus center. X-ray crystallographic analysis combined with NMR, UV/vis, IR spectroscopic, and electrochemical studies, supported by theoretical calculations, revealed the crucial role of the phosphorus atom for the unique redox, structural
合成了一种稳定的双电子受体,该双电子受体包含一个由二氰基亚甲基桥连的cri啶膦骨架,并通过磷中心的衍生化有效地调节了它们的可逆还原电位。X射线晶体学分析结合NMR,UV / vis,IR光谱和电化学研究,并得到理论计算的支持,揭示了磷原子对于这些化合物独特的氧化还原,结构和光物理性质的关键作用。结果确定了这些缺电子支架在进一步功能化后对开发功能性n型材料和氧化还原活性发色团的潜力。
