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.

Organic bulk heterojunction (BHJ) solar cells based on small molecular donors have received great attentions recently, because small molecules possess the merits of high purity, well-defined molecular structures, definite molecular weights and high charge carrier mobility. The highest power conversion efficiency (PCE) of BHJ solar cells based on small molecular donors and fullerene derivative acceptors has reached 7.38%. In this review, we will briefly summarize the development of small molecular donor based BHJ solar cells in the past two years. These results suggest that small molecular donors are promising candidates for high efficiency BHJ solar cells. Due to the environmental constraints and the predicatable exhaustion of fossil energy resources, it is one of the major challenges in the 21st century to find clean and renewable energy. Solar energy which has the potential to act as renewable and clean energy sources is believed one of the promising and long term alternatives to replace fossil energy in the future. Currently, solar cells based on silicon have been practically applied, however, the high cost hinders their wide applications. Comparing with the well-studied silicon solar cells, photovoltaic devices based on organic semiconductors have attracted great attentions recently because they can be fabricated on flexible substrate with large scale at low-cost [1,2]. In this review, we will mainly focus on the development of organic BHJ solar cells. Organic BHJ solar cells consist of electrodes (cathode and anode), donor and acceptor blended active layer and substrate. Based on the donor used into solar cells, they can be briefly divided into two classes, polymer donor solar cells and small molecular donor solar cells. Currently, the polymer donor solar cells have made great progress [3][4][5][6][7], and the highest power conversion efficiency (PCE) reported in literatures has been over 8% [8,9]. In spite of the high performance, there are disadvantages for polymer donors [10], for instance, the high molecular weight dispersity, the batch to batch reproducibility, and so on. On the other hand, small molecular donors do not have the drawbacks mentioned above. In contrast, they have high purity, well-defined molecular structures, definite molecular weights, as well as high charge carrier mobility [11]. As a result, small molecular donors have attracted more and more attentions for photovoltaic applications recently and the highest PCE of BHJ devices based on small molecular donors has reached 7.38% [12].Considering several reviews have summarized the application of small molecular donors in BHJ solar cells [13][14][15][16][17][18][19][20][21], in the present review, we will mainly focus on the development of small molecular donor BHJ solar cells in the past two years. The review will classify the donors based on their device fabrication technique. And the principle of organic solar cells which can be found in the previous reviews
