This review highlights the recent developments in the field of metalloporphyrins as optical probes for biologically relevant molecules, such as nitric oxide (NO) and hydrogen sulfide (H2S), and as catalysts for the preparation of sustainable polymers such as polyesters, by the ring-opening polymerization (ROP) of cyclic esters and the ring-opening co-polymerization (ROCOP) of epoxides and anhydrides, and polycarbonates by the chemical fixation of carbon dioxide (CO2). The great potential of porphyrins is mainly due to the possibility of making various synthetic modifications to the porphyrin ring, such as modifying the coordinated metal, peripheral substituents, or even the molecular skeleton. Due to the strict structure-property relationships, one can use porphyrinoids in several different applications such as, for instance, activation of molecular oxygen or catalysis of photosynthetic processes. These possibilities broaden the application of porphyrins in several different fields of research, further mimicking what nature does. In this context, here, we want to provide evidence for the great flexibility of metalloporphyrins by presenting an overview of results obtained by us and others in the research fields we are currently involved in. More specifically, we report a survey of our most significant achievements regarding their use as optical probes in the context of the results reported in the literature from other research groups, and of the use of porphyrin metal(iii) complexes as catalysts for sustainable polymerization processes. As for the optical probe section, in addition to the metalloporphyrins synthesized ad hoc in the laboratory, the present work also covers the natural proteins containing a porphyrin core.
这篇综述重点介绍了金属卟啉作为生物相关分子（如一氧化氮（NO）和硫化氢（H2S））的光学探针，以及作为催化剂用于制备可持续聚合物（如聚酯、环状酯的开环聚合（ROP）和环氧化物和酸酐的开环共聚（ROCOP）以及通过二氧化碳（CO2）的化学固定制备聚碳酸酯）的最新进展。卟啉的巨大潜力主要归因于对卟啉环进行各种合成修饰的可能性，例如修饰配位金属、外围取代基，甚至分子骨架。由于严格的结构-性质关系，人们可以将卟啉类化合物应用于几种不同的应用，例如分子氧的活化或光合作用过程的催化。这些可能性拓宽了卟啉在几个不同的研究领域的应用，进一步模拟了自然界的作用。在这种情况下，我们希望通过介绍我们和其他研究小组在我们目前参与的研究领域中获得的结果，为金属卟啉的巨大灵活性提供证据。更具体地说，我们报告了我们在将金属卟啉用作光学探针方面的一些最显著成就的调查，包括在文献中报道的其他研究小组的结果背景下，以及在可持续聚合过程中使用卟啉金属（iii）配合物作为催化剂的情况。对于光学探针部分，除了在实验室中专门合成的金属卟啉外，本工作还涵盖了含有卟啉核心的天然蛋白质。
