“…In a parallel investigation, Jiang and co‐workers created a host–guest supramolecular polymer through assembly of a four‐armed guest molecule, 5,10,15,20‐tetrakis( N ‐carboxymethyl‐4‐pyridinium)porphyrin tetrabromide ( 15 ) with tetramethylcucurbit[6]uril 29. The strong host–guest interaction and hydrogen‐bonding interactions between the tetramethylcucurbit[6]uril molecules led to the formation of a two‐dimensional supramolecular polymer network.…”

This Minireview focuses on the very recent developments in the field of porphyrin‐based self‐assembled nanomaterials with a particular focus on the use of tetrapyrrolic macrocycles bearing amphiphilic and ionic functionalities. As one of the most studied molecular materials, the importance of porphyrin‐derived nanomaterials has attracted wide interest in many applications like catalysis, photodynamic therapy, and organic solar cells to name a few. By using key examples that have recently appeared in the literature, the discussion unfolds through two sections: amphiphilic and ionic assemblies. Although it focuses on the nanostructuring methodologies used to obtain organized materials, the discussion will also target the physical characterization of the functional materials for their implementation in prototypes.

More than three dozen different metal ions have been incorporated into the macrocyclic core of water-soluble tetra-N-methylpyridylporphyrins, and many of these complexes have been studied with respect to their physicochemical [1][2][3][4][5][6][7][8][9] and electrochemical [10][11][12][13][14][15][16][17][18][19][20][21][22] properties in both aqueous and nonaqueous media. These compounds are easily reducible in both water and nonaqueous solvents, and an umber of the complexes have been used in nuclear medicine, [21,[23][24][25][26] examples being given by tetra-N-methylpyridylporphyrins having the formula [M(TMPyP)] n + (X À ) n where TMPyP represents the porphyrin macrocycle with four meso-substituted N-methylpyridyl groups, n = 4o r5 ,X À = an anion and M = In II ,Mn III ,Fe III ,o rG d III .The electrochemistry of [M(TMPyP)] n + (X À ) n in nonaqueous media has been characterizeda lmoste xclusively with respect to the reductionst hat can occur at the conjugated p-ring system of the macrocycle, the electroactive N-methylpyridyl substituents, and, in some cases, at the central metal ions. Early electrochemical studies of these compounds were carried out in DMF,D MSO,a nd acetonitrile, [1,3,27] all of which possess [a] Y.

The versatility of porphyrins as optoelectronic or catalytic units makes them attractive elements for inclusion in functional materials. Polymers that include porphyrins have been created with a wide variety of structures and used in a wide range of applications. This review covers recent developments in the synthesis, characterization and applications of polymeric materials in which porphyrins are key components of the repeat units, including the rapidly growing area of metal-organic frameworks and related covalent organic frameworks. © 2015 Society of Chemical Industry Keywords: review; porphyrin; metal-organic framework; covalent organic framework PORPHYRINS AS FUNCTIONAL BUILDING BLOCKSThe porphyrin ring and its many structural relatives are common functional units in both natural and synthetic systems (Fig. 1). Porphyrins have a variety of properties that allow them to be useful in applications, especially their broad-ranging optoelectronic and catalytic capabilities. Furthermore, these properties are readily modulated by incorporation of various metals inside the ring or by substituent effects at various locations around the ring. In many cases, nature provides guidance for specific structure-function correlations and applications -the so-called biomimetic approaches. In nature, porphyrin (heme) units are typically embedded in a biological matrix that controls the environment of and access to the porphyrin. In synthetic systems, porphyrins in polymeric matrices have been developed in similar fashion to help control the specific application.In this review, we briefly cite previous reviews and summarize recent results regarding the synthesis, structure, properties and applications of polymeric porphyrins. We only include polymers that contain multiple porphyrin units as an integral part of the polymer, as opposed to polymeric matrices that are simply used to encapsulate individual porphyrin units. We also cover the rapidly growing field of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), where they specifically include porphyrins as a key component of the framework. Structures related to porphyrins (phthalocyanines, corroles, chlorins, etc.) and porphyrin dimers are not covered, but some porphyrin oligomers are discussed; reviews on many of these are available in the comprehensive series Handbook of Porphyrin Science.
