Citric acid, an important metabolite with abundant reactive groups, has been demonstrated as a promising starting material to synthesize diverse photoluminescent materials including small molecules, polymers, and carbon dots. The unique citrate chemistry enables the development of a series of citric acid-based molecules and nanomaterials with intriguing intrinsic band-shifting behavior, where the emission wavelength shifts as the excitation wavelength increases, ideal for chromatic imaging and many other applications. In this review, we discuss the concept of "intrinsic band-shifting photoluminescent materials", introduce the recent advances in citric acid-based intrinsic band-shifting materials, and discuss their potential applications such as chromatic imaging and multimodal sensing. It is our hope that the insightful and forward-thinking discussion in this review will spur the innovation and applications of the unique band-shifting photoluminescent materials.
柠檬酸是一种具有丰富反应基团的重要代谢物，已被证明是合成多种光致发光材料（包括小分子、聚合物和碳点）的有前景的起始原料。独特的柠檬酸盐化学性质使得能够开发出一系列具有有趣的固有带移行为的基于柠檬酸的分子和纳米材料，其中发射波长随着激发波长的增加而移动，这对于彩色成像和许多其他应用来说是理想的。在这篇综述中，我们讨论了“固有带移光致发光材料”的概念，介绍了基于柠檬酸的固有带移材料的最新进展，并讨论了它们在彩色成像和多模态传感等方面的潜在应用。我们希望这篇综述中富有洞察力和前瞻性的讨论将推动独特的带移光致发光材料的创新和应用。
