摘要

2024年12月27日，中国化工学院化学纤维与高分子材料改性国家重点实验室顾丹丹、陈佳、孙斌等专家团队在《广东金融时报》上发表了一篇文章，介绍了其在荧光增强领域的研究进展。该团队合成了一种苝二亚胺衍生物PDI-COOH，当与钙离子在THF/H2O溶液中结合时，其荧光明显增强。他们研究了PDI-COOH/Ca2+在不同水合状态下的组装和荧光行为，提出了PDI-COOH/Ca2+在THF/H2O和THF中的荧光发射机制。这项工作揭示了一种新的聚合态荧光增强策略，并强调了水在分子荧光发射和组装中的重要作用。

Complexation and Fluorescence Enhancement of Bay-site Carboxyl Modified Perylene Dimide with Calcium Ion

On December 27, 2024, a team of experts led by GU Dandan, CHEN Jia, SUN Bin from the School of State Key Laboratory for Modification of Chemical Fibers and Polymer Materials published an article in the 发光学报, introducing its research progress in the field of fluorescence enhancement. The team synthesized a perylene diimide derivative, PDI-COOH, which showed distinctive enhanced fluorescence when combined with calcium ion in THF/H2O solution. They studied the assembly and fluorescence behavior of PDI-COOH/Ca2+ under different hydration states, proposing the fluorescence emission mechanism of PDI-COOH/Ca2+ in THF/H2O and THF. This work reveals a novel strategy of aggregated state fluorescence enhancement and highlights the important role of water in molecular fluorescence emission and assembly.

期刊介绍： Chinese Journal of Luminescence (CJL), supervised by Chinese Academy of Sciences (CAS), Sponsored by Committee on luminescence of Chinese Physical Society and Changchun Institute of Optics, Fine mechanics and Physics（CIOMP）of Chinese Academy of Sciences, is an authoritatively scientific and technical periodical of China in the field of luminescence, which is read widely in providing original papers and reviews that describe recent developments on basic theory and experimental studies of excited state processes and green lighting projects. The journal was established at 1980, and named after LUMINESCENCE AND DISPLAY, then renamed as CJL in 1986.
