BODIPY Couple in Aqueous Media
OS-EN-023 Novel Luminogens for Aggregation Induced Emission Enhancement: A Highly Fluorescent TPEBODIPY Couple in Aqueous Media Serdar Atılgan Süleyman Demirel University, Chemistry Department, Isparta, Turkey Herein, we described a new way of emission enhancement for BODIPY dyes by means of decorating with TPE units and exploiting the hydrophobic effect to induce restriction on the emission quenching free rotations of their phenyl rings. Our approach to tackle the emission quenching observed for several BODIPY dyes in aqueous solutions has proved efficient in constructing an AIE active BODIPY luminogen, which, although it is highly hydrophobic, has high emission intensities both in aqueous solutions and in solid state.
