Together these findings suggested that oxidative doping might produce a conductive material and, indeed, this is case. The changes in the mean atomic partial charges (Supplementary Table 1) are largest for the gold-thiolate backbone but with some contribution from the nucleobase. The complexation reaction with Au(I) ions spontaneously assembles luminescent one-dimensional helical chains, characterized as n chain and the nucleobase (Fig. Here, we demonstrate this with a coordination polymer derived from 6-thioguanosine (6-TG-H), a sulfur-containing analog of a natural nucleoside.
However, the routine integration of semiconducting properties, particularly long-range electrical conduction, into the basic topological motif of DNA remains challenging. Advances in bottom-up material design have been significantly progressed through DNA-based approaches.
