Fluorescent nucleobase surrogates capable of Watson-Crick hydrogen bonding are essential probes of nucleic acid structure and dynamics. Their limited brightness and short absorption and emission wavelengths have rendered them unsuitable for single-molecule detection. Herein, we synthesized a new tricyclic pyrimidine nucleoside analogue with a push-pull conjugated system.

Single-molecule fluorescence measurements of ABN using both one-photon and two-photon excitation demonstrate its excellent photostability and indicate that the nucleoside is present to >95% in a bright state with count rates of at least 15 kHz per molecule. This new fluorescent nucleobase analogue, which, in duplex DNA, is the brightest and most red-shifted known, is first to offer robust single-molecule fluorescence detection capabilities.
