Pyrrole- and indole-linked C8-deoxyguanosine nucleosides act as fluorescent reporters of H-bonding specificity. Their fluorescence is quenched upon WatsonâCrick H-bonding to dC, while Hoogsteen H-bonding to G enhances emission intensity. The indole-linked probe is â¼ 10-fold brighter and shows promise as a fluorescent reporter of Hoogsteen base pairing.
