Research Abstract

We have successfully fabricated doped Cu-TCNQ nanocrystals, using the co-precipitation method involving a chemical reduction process, which took the composition ratio of Cu:TCNQ = 1.3:1 and contained both TCNQ anion and dianion. Interestingly, the doped nanocrystals exhibited a new strong absorption in near-infrared (NIR) region, clearly dependent on the content of the TCNQ dianion.
