Fluorescent dyes are an indispensable part of the scientific enterprise. Xanthene-based fluorophores, such as fluorescein and rhodamine, have been in continual use across numerous fields since their invention in the late 19th century. Modern methods to synthesize and expand the scope of xanthene dye chemistry have enabled new colors, enhanced stability, and improved brightness. Modifications to the 3-position of xanthene dyes have been, until recently, less well-explored. Here, we discuss how small changes to the identity of the substituent at the 3-position of fluoresceins and rhodamines can profoundly alter the properties of xanthene dyes, with the potential to unlock new applications at the interface of chemistry and biology.
荧光染料是科学事业不可或缺的一部分。自 19 世纪晚期发明荧光素和罗丹明等基于荧蒽的荧光体以来，它们一直被广泛应用于各个领域。现代方法合成并扩大了氧杂蒽染料化学的范围，使其能够产生新的颜色、增强稳定性并提高亮度。直到最近，对呫吨染料 3 位的改性还没有得到很好的探索。在这里，我们将讨论荧光素和罗丹明 3 位取代基身份的微小变化是如何深刻改变氧杂蒽染料的特性的，从而有可能在化学和生物学的交界处开启新的应用。

Bioelectrochemical systems using electroactive microorganisms have applications including energy generation, microbial electrosynthesis, electrofermentation, and biosensing. Enhancing extracellular electron transfer (EET) between microorganisms and electrodes in these systems is a rapidly evolving field. This Review presents recent and emerging advances in the development of novel electrode materials, including incorporation of conductive polymers (CPs), common nanomaterials, MXenes, and metal–organic frameworks (MOFs) to increase the conductivity and surface area available for microbial electrochemical reactions. We also discuss electrodes of the future, focusing on computational rational design and approaches that consider the microorganisms’ perspective in the design process. These include patterning to achieve biologically relevant surface architecture and mimicking the extracellular matrix to form artificial biofilms.

Emerging green approaches for valorization of plastics with saturated carbon backbones 对具有饱和碳骨架的塑料进行价值评估的新兴绿色方法

Plastics possess highly unsustainable linear life cycles that are environmentally damaging. With low recycling rates worldwide, plastics upcycling is emerging as a promising alternative by using these abundant waste products as chemical feedstock for the production of materials and essential chemicals of higher economic value. However, the saturated C–C polymer backbones of polymers constituting ~60% of all plastic waste are unreactive and challenging to upcycle, often necessitating energy-intensive processes. This review examines state-of-the-art sustainable approaches employing the Principles of Green Chemistry to functionalize or cleave these unreactive polymer backbones, including alternative solvents, Earth-abundant metal catalysis, emerging low-energy approaches, and biocatalysis. Such sustainable strategies will enhance the attractiveness and practical feasibility of plastics upcycling to achieve a circular materials economy.

塑料具有非常不可持续的线性生命周期，会对环境造成破坏。由于全球范围内的回收率较低，塑料升级再循环正成为一种前景广阔的替代方法，即利用这些丰富的废品作为化学原料，生产具有更高经济价值的材料和基本化学品。然而，占所有塑料废弃物约 60% 的饱和 C-C 聚合物骨架不具反应性，很难进行升级再循环，通常需要采用能源密集型工艺。本综述探讨了利用绿色化学原理对这些无反应的聚合物骨架进行功能化或裂解的最先进的可持续方法，包括替代溶剂、地球富集金属催化、新兴低能耗方法和生物催化。这些可持续战略将增强塑料升级再循环的吸引力和实际可行性，从而实现循环材料经济。
