A historical perspective on porphyrin-based metal–organic frameworks and their applications

Porphyrin based metal–organic frameworks: highly sensitive materials for optical sensing of oxygen in gas phase

“…Porphyrins are excellent organic linkers for the construction of MOFs and many different frameworks have been described over the last decades. 27,28 Unfortunately, many of them are prone to hydrolysis 29 and are therefore of limited interest for sensing applications under ambient conditions. One well-described and hydrolytically considerably stable porphyrin-based MOF is PCN-224.…”

“…30 These properties render PCN-224 and closely related MOFs attractive for many applications such as (photo)catalysis, [31][32][33] photodynamic therapy 34,35 or drug delivery. 27,36,37 However, the luminescence properties of the PCN-224 in context of oxygen sensing in the gas phase have not been investigated. Only the Pt(II) derivative of PCN-224, Pt(II)PCN-224, was used for real-time monitoring of dissolved oxygen in aqueous dispersion.…”

Porphyrin and phthalocyanine-based metal organic frameworks beyond metal-carboxylates

“…Note that the synthesis and commercial availability of functionalised phthalocyanine ligands is more limited for now. Few review articles described the state of the art of porphyrinbased MOFs in the past years, [33][34][35][36] where the great majority of examples concerned the above-mentioned carboxylate and pyridyl functionalities. In this review, we wish to highlight the development of porphyrin and phthalocyanine MOFs based on non-carboxylate anionic linkers potentially featuring original and for now less developed architectures, as well as new properties.…”
