Red‐Emissive Fluorescein Derivatives and Detection of Bovine Serum Albumin

Red light: Two fluorogenic compounds were synthesized by derivatization of 2′,7′-dichlorofluorescein at the C4′ and C5′ positions. These compounds have excellent photostability and emit at red wavelengths. Both compounds are highly selective for detecting bovine serum albumin because of their particular dyad structures.
