文摘

A novel red aggregation-induced emission enhancement (AIEE) chromophore was synthesized utilizing palladium-catalysed Heck reaction. It emitted the strongest deep-red fluorescence in 90% THF/water, performing typical deep-red aggregation-induced fluorescence enhancement. The fluorescence intensity of OPA-BODIPY enhanced with increasing concentration of bovine serum albumin (BSA) which showed OPA-BODIPY could function as bioprobe for BSA. It was applied to cell imaging and showed a good uptake by MDA-MB-231 cells.
