We report a concise post-modification method to convert an electroneutral triazole-linked DNA (TLDNA) to a positively charged triazolium-linked analogue, TLDNA+. A one-step methylation of oligothymine TLDNA successfully afforded TLDNA+ with a dramatic improvement in the solubility. The pentameric oligothymine TLDNA+ formed a stable triple helix with natural oligoadenine DNA as well as a mercury-mediated self-duplex.
