Bioluminescence, wherein marine and terrestrial organisms chemically produce light for communication, is a burgeoning area of research. Herein, we demonstrate a new series of artificial chemiluminescent compounds inspired by the enol-degradation reaction of natural bioluminescent molecules, luciferins. Based on systematic optical experiments, isotope labeling, and theoretical calculations, the chemiluminescent mechanism of these new materials and the relationship of enol-degradation reaction and chemiluminescence are fully discussed. The color and efficiency of the artificial chemiluminescent materials can be easily adjusted, and blue (486 nm), yellow (565 nm), and near-infrared (756 nm) luminescence can thus be obtained. The findings and in-depth understanding herein may accelerate the development of bio/chemiluminescent materials for analytical applications and non-invasive bioluminescence imaging.
生物发光是一个新兴的研究领域，在这个过程中，海洋和陆地生物通过化学反应产生光用于交流。在此，我们展示了一系列受天然生物发光分子荧光素的烯醇降解反应启发而合成的新型人工化学发光化合物。基于系统的光学实验、同位素标记和理论计算，全面讨论了这些新材料的化学发光机制以及烯醇降解反应与化学发光的关系。人工化学发光材料的颜色和效率可以很容易地调节，从而可以获得蓝色（486纳米）、黄色（565纳米）和近红外（756纳米）发光。本文的研究结果和深入理解可能会加速用于分析应用和非侵入性生物发光成像的生物/化学发光材料的开发。
