Abstract:

A novel water-soluble conjugated macrocyclic tetramaleimide (WCMT-1) with far red/near-infrared (FR/NIR) fluorescence emission has been rationally designed and successfully synthesized. WCMT-1 with the twisted donor (D) and acceptor (A) structures make it possess both aggregation-induce emission (AIE) and twist intramolecular charge transfer (TICT) characteristics. Due to the AIE effects, WCMT-1 exhibits a strong fluorescence in non-polar solvents (the quantum yield of WCMT-1 reaches to 33.7% in toluene and 32.5% in CCl4), but it is quenched in an aqueous solution caused by the TICT process. However, by the introduction of sodium lauryl sulfonate (SLS) into the WCMT-1 aqueous solution, the in situ generated WCMT-1&SLS supra-amphiphile resulted in remarkable recovery of FR/NIR fluorescence. Furthermore, combined with its large Stokes shift and good water solubility, the bioimaging experiments towards HeLa and HepG2 cells have also been conducted to give a good performance.
