Donor and acceptor engineering for BINOL based AIEgens with enhanced fluorescence performance

Abstract

A D–π–A strategy enhances aggregation-induced emission performance with a large Stokes shift over 200 nm.

Structures and Applications of NIR‐II AIEgens Containing Benzobisthiadiazole Derivatives

“…[14] Recently, AIEgens have been widely used as advanced functional materials in sensing and imaging, specific cancer cell imaging and therapeutics due to high biological stability, low background noise, good biocompatibility and low toxicity. [15][16][17][18][19] In imaging, shallow penetration depth has been hindering the development of clinical application of fluorescence imaging. [20] According to the biological transparency window, the near-infrared (NIR) biological region can be divided into NIRÀ I (650-950 nm), NIR-II (1100-1350 nm), NIR-III (1600-1870 nm) and NIR-IV (2100-2300 nm) windows.…”
