“…The average molecular weights reported were 4.1 and 8.5 kDa with polydispersities of 1.38 and 1.35 (for the polymers in Figs (a) and (b), respectively). The latter polymer had a lower band gap and a significantly broader absorption which led to a higher conversion efficiency of 1.26% in the PSCs tested …”

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.

“…The PL spectra exhibited broad absorption in the 300-650 nm regions while CV showed a reduction in the LUMO energy level occurs upon introduction of an electron-deficient dithiophenylbenzothiadiazole thiophene adjacent to the benzodithiophene units in the main chain. 117 Similarly, novel alternating D-A copolymers (50) were synthesised by step-growth polymerisation using the Sonogashira cross-coupling reaction between POR dialynes and diiodoaryl monomers (M n = 25 800-61 700; PDI = 1.18-1.31). Owing to the doublystrapped porphyrin linkages in the polymer backbone, these copolymers exhibit orthogonally and alternately arrayed transition dipoles.…”
