A novel family of AIE-active <i>meso</i>-2-ketopyrrolyl BODIPYs: bright solid-state red fluorescence, morphological properties and application as viscosimeters in live cells

Abstract

AIE-active and bright solid-state red-emissive <italic>meso</italic>-2-ketopyrrolyl BODIPYs have been developed as viscosimeters in live cells for real-time quantification of intracellular viscosities.
