Used in organic synthesis and materials science, particularly in the development of fluorescent probes and sensors. Its pyrene moiety provides strong fluorescence, making it useful for bioimaging and detection of biomolecules. The alkyne group allows for click chemistry applications, enabling efficient conjugation with azide-containing molecules in labeling and bioconjugation processes. Also employed in the design of functional polymers and supramolecular systems due to pyrene's stacking ability. Common in research settings for studying molecular interactions and cellular processes.
