这项工作为开发红光激发近红外余辉材料提供了一种可行的分子设计策略,研究组还成功地将该材料应用于无自体荧光生物成像,在保持与主体材料相容性的同时, Ping, Wu,展现出具有多种性能(衰减路径、寿命、发射波长)的可见光激发余辉,得益于扭曲的分子构型和较小的能隙, 将激发和发射波长延伸至红光乃至近红外区域。
是有机余辉材料领域极具挑战性且具有重要科学价值的研究课题, Jiang,研究组提出了一种扭曲分子内电荷转移型掺杂剂分子设计策略,即用富电子取代基修饰长寿命的缺电子掺杂剂, Zhiqin, Xiang IssueVolume: 2026-06-10 Abstract: Extending the excitation and emission wavelengths into the red or even near-infrared region is a highly challenging yet scientifically valuable research topic in the field of organic afterglow materials. To solve this issue。

该研究于2026年6月10日发表于在《光:科学与应用》杂志上。

the maximum emission wavelength of the afterglow extends to 725nm (=67.82ms). We also successfully apply this material in autofluorescence-free bioimaging. This work provides a viable molecular design strategy for developing red-light-excitable near-infrared afterglow materials and demonstrates their potential for in vivo bioimaging.
