报告摘要：BODIPY (boron-dipyrromethene) dyes are a versatile class of fluorescent organic molecules that exhibit exceptional photophysical properties, including sharp absorption and emission bands spanning the visible to near-infrared (NIR) regions, high fluorescence quantum yields, and excellent photostability. Regioselective introduction of ethynyl groups via direct C–H activation of the BODIPY core enables precise extension of π-conjugation and fine modulation of excited-state dynamics, leading to unique and tunable optical properties. In this lecture, I will highlight how these molecular designs have been exploited as promising NIR-active materials for viscosity-dependent fluorescent sensing, two-photon–excited photoacoustic imaging, photothermal therapy, polariton lasers, and artificial light-harvesting antennae, with an emphasis on structure–property–function relationships.
