Endowing a triarylboron compound showing ACQ with AIE characteristics by transforming its emissive TICT state to be dark†
Abstract
A triarylboron-based AIE fluorophore, TAB-AIE-FL, was designed and synthesized by introducing an electron acceptor to boost charge separation, transforming its TICT state from bright emission to dark. We further introduced it into NIH/3T3 cells using nanogel as a carrier for imaging the intracellular environments of cytoplasm and nucleus.
