摘要：NOVELTY - A borofluoro-diisoindole derivative (I) is new. USE - New borofluoro-diisoindole derivative is used as near-infrared fluorescent dye. ADVANTAGE - The borofluoro-diisoindole derivative has excellent photochemical activity and physical property, and maximum ultraviolet absorption wavelength of 640-680 nm and maximum fluorescence emission wavelength of 670-713 nm, and increases conjugation of ( pi )-bonds in parent molecule. DETAILED DESCRIPTION - A borofluoro-diisoindole derivative of formula (I) is new. R1=halo or halo-1-3C alkyl;and R2,R3=H or 1-3C alkoxy. An INDEPENDENT CLAIM is included for preparation of borofluoro-diisoindole derivative (I).
