容易获得的室温稳定的有机混合价化合物通过由各种间隔基桥接的环状双（亚胺鎓）盐[衍生自环状（烷基）（氨基）卡宾]的单电子还原来制备。这些化合物在近红外（NIR）中显示出特征的价间电荷转移（IV-CT）带。循环伏安法、EPR、IR、UV-vis和X-射线研究以及DFT计算表明，根据间隔基的性质，这些混合价化合物的范围从III类到II类。
Readily available room temperature stable organic mixed valence compounds are prepared by one-electron reduction of cyclic bis(iminium) salts [derived from cyclic (alkyl)(amino)carbenes] bridged by various spacers. These compounds show characteristic intervalence charge transfer (IV-CT) bands in the near-infrared (NIR). Cyclic voltammetry, EPR, IR, UV-vis, and X-ray studies, as well as DFT calculations, show that, depending on the nature of the spacer, these mixed valence compounds range from class III to class II.
