Three new ligands based on the alloxazine core appended with pyridyl coordinatinggroups have been designed, synthesized, and characterized. The ligands are revealed to be redox-active in DMF solution, as attested to by CV and combined CV/EPR studies. The spin of the reduced species appears to be delocalized on the alloxazine core, as attested to by DFT calculations. The coordination abilities of one
设计、合成并表征了三种基于咯嗪核附加吡啶基配位基团的新配体。 CV 和 CV/EPR 联合研究证明,配体在 DMF 溶液中具有氧化还原活性。 DFT 计算证明,还原物质的自旋似乎在咯嗪核上离域。其中一个配体对 Cu 2+或 Ni 2+ 3d 阳离子的配位能力揭示了第一个基于咯嗪的 3D 配位聚合物的形成,呈现出强烈的 π-π 堆积和大量空腔。锂电池的初步充电/放电实验证明了 Li +插入到此类系统中。
