In this communication, three novel donor–acceptor–donor type second near-infrared AIE fluorophores based on strong electron-acceptor 2,2′-(anthracene-9,10-diylidene) dimalononitrile have been successfully developed for bioimaging, in which they exhibit good photostability and can be used in mouse ear vessel imaging with high resolution (FWHM = 93.4 μm/SBR = 1.5) after capsuling in nanoparticles with good biocompatibility.

基于强电子受体2,2'-（蒽-9,10-二亚甲基）二甲基腈的聚集诱导发射荧光团在NIR-II窗口中的生物成像

在这次交流中，成功开发了基于强电子受体2,2'-（蒽-9,10-二亚甲基）二丙二腈的三种新颖的供体-受体-供体型第二近红外AIE荧光团，它们在生物成像中表现出良好的光稳定性，并囊封在具有良好生物相容性的纳米颗粒后，可用于高分辨率（FWHM = 93.4μm/ SBR = 1.5）的小鼠耳血管成像。
