Porphyrins and porphyrin derivatives have been intensively explored for a number of applications such as sensing, catalysis, adsorption, and photocatalysis due to their outstanding photophysical properties. Their usage in sensing applications, however, is limited by intrinsic defects such as physiological instability and self-quenching. To reduce self-quenching susceptibility, researchers have developed porphyrin metal-organic frameworks (MOFs). Metal-organic frameworks (MOFs), a unique type of hybrid porous coordination polymers comprised of metal ions linked by organic linkers, are gaining popularity. Porphyrin molecules can be integrated into MOFs or employed as organic linkers in the production of MOFs. Porphyrin-based MOFs are a separate branch of the huge MOF family that combines the distinguishing qualities of porphyrins (e.g., fluorescent nature) and MOFs (e.g., high surface area, high porosity) to enable sensing applications with higher sensitivity, specificity, and extended target range. The key synthesis techniques for porphyrin-based MOFs, such as porphyrin@MOFs, porphyrinic MOFs, and composite porphyrinic MOFs, are outlined in this review article. This review article focuses on current advances and breakthroughs in the field of porphyrin-based MOFs for detecting a variety of targets (for example, metal ions, anions, explosives, biomolecules, pH, and toxins). Finally, the issues and potential future uses of this class of emerging materials for sensing applications are reviewed.

用于化学和生物传感的卟啉金属有机框架传感器

由于其优异的光物理性质，卟啉和卟啉衍生物在传感、催化、吸附和光催化等许多应用中得到了广泛的探索。然而，它们在传感应用中的使用受到生理不稳定性和自猝灭等内在缺陷的限制。为了降低自猝灭敏感性，研究人员开发了卟啉金属有机框架（MOF）。金属有机框架（MOF）是一种独特的杂化多孔配位聚合物，由有机连接体连接的金属离子组成，越来越受欢迎。卟啉分子可以整合到 MOF 中或用作 MOF 生产中的有机连接体。基于卟啉的 MOF 是庞大 MOF 家族的一个独立分支，它结合了卟啉（例如荧光性质）和 MOF（例如高表面积、高孔隙率）的独特品质，使传感应用具有更高的灵敏度、特异性和扩展能力。目标范围。本文概述了基于卟啉的 MOF（例如卟啉@MOF、卟啉 MOF 和复合卟啉 MOF）的关键合成技术。本文重点介绍用于检测各种目标（例如金属离子、阴离子、爆炸物、生物分子、pH 和毒素）的卟啉基 MOF 领域的当前进展和突破。最后，回顾了此类新兴材料在传感应用中的问题和潜在的未来用途。
