An innovative class of aminochromene-aniliniumion conjugated far-red to near-infrared dyes, namely ACA, was developed. The design method for ACA dyes is straightforward and the synthesis of the ACA dyes is rapid and convenient. The ACA dyes display absorption and emission in the far-red to near-infrared region, good photostability and chemical stability. The ACA dyes could be used for bio-imaging not only in living cells but also in living animals. The design method described herein may be applicable to other types of long wavelength dyes and the ACA dyes may find interesting applications as sensing and labelling agents in diverse fields.
开发了一类创新的氨基色烯 - 苯胺离子共轭的远红到近红外染料，即ACA。ACA染料的设计方法简单直接，其合成快速且方便。ACA染料在远红到近红外区域显示吸收和发射，具有良好的光稳定性和化学稳定性。ACA染料不仅可用于活细胞中的生物成像，还可用于活体动物。本文所述的设计方法可能适用于其他类型的长波长染料，并且ACA染料可能在不同领域中作为传感和标记剂找到有趣的应用。
