Problems solved by technology

However, the metal-tetracyanoquinone dimethane electron transfer complex has extremely low solubility in commonly used organic solvents, and is only slightly soluble in a few non-used solvents such as acetonitrile, (such as copper-tetracyanoquinone dimethane The solubility of the electron transfer complex of derivatives in acetonitrile is: 0.03mg / ml), it is difficult to adopt the easy-to-practice and low-cost spin-coating method to form, thus greatly hindering the application of this compound in the above-mentioned fields
