A new donor-acceptor conjugated copolymer (PDTPyDPP), comprising 2,7-di-2-thienyl-4,5,9,10-tetrakis(hexyloxy)pyrene as a donor and diketopyrrolopyrrole (DPP) as an acceptor, was synthesized. PDTPyDPP showed good solubility in common organic solvents, broad visible absorption from 300 to 900 nm, and a moderate hole mobility up to 6.3 × 10-3 cm2 V-1 s-1. The power conversion efficiency of the photovoltaic device based on the PDTPyDPP/PC71BM photoactive layer reached 4.43% with 0.66 V of open-circuit voltage (Voc), 10.52 mA cm-2 of short-circuit current (Jsc) and 64.11% of fill factor.

The preparation of membranes with high selectivity based on specific chemical properties such as size and charge would impact the efficiency of the world's energy supply, the production of clean water, and many other separation technologies. We report a flexible synthetic protocol for preparing highly ordered two-dimensional nanoporous polymeric materials (termed covalent organic frameworks or COFs) that allow for placing virtually any function group within the nanopores. We demonstrate that membranes, fabricated with this new family of materials with carboxylated pore walls, are very water permeable, as well as highly charged and size selective.

Three donor–acceptor–donor (D–A–D) pyrene chromophores are described and compared by DFT computations. The two properties of low energy photon absorption and low energy electrochemical reduction are demonstrated through a pyrene framework. Altering the electron-acceptor strength of the pyrene core by chemical oxidation or installation of a thiadiazole dioxide heterocycle results in the formation of D–A–D chromophores with absorption bands up to 900 nm and LUMO energy levels of approximately –4.1 eV vs. vacuum.

An efficient synthesis of 2,7-dibromo- and diiodo-pyrene(4,5,8,19)- tetraones led to strong donors and acceptors based on pyrene. They are versatile building blocks for conjugated materials and can be further applied in molecular electronics. The Royal Society of Chemistry 2013.

Organic materials have attracted extensive attention for use in lithium-ion batteries due to the flexible designability of their structures and their high theoretical capacities. However, the high solubilities, low voltages, and poor conductivities of traditional organic materials have impeded their further application. Herein, a novel carbonyl-rich covalent organic polymer (COP), polyphenyl-1,3,5-(pyrene-4,5,9,10-tetraone) (PPh-PTO), was designed and synthesized.In situFourier-transform infrared spectroscopy (FTIR),ex situX-ray photoelectron spectroscopy (XPS), and Raman analysis were used to confirm the carbonyl redox-active centers. Moreover, density functional theory (DFT) calculations were used to verify that the extended conjugated structure can induce electron delocalization and achieve an elevated and slanted voltage plateau in comparison with the pyrene-4,5,9,10-tetraone (PTO) monomer. The extended structure enables PPh-PTO to show a high reversible capacity of 235 mA h g?1at 0.1 A g?1, superior cycling abilities (95% capacity retention after 1400 cycles), and excellent rate performance (94 mA h g?1at 2 A g?1) in lithium-ion batteries. Our work developed a promising strategy for designing high-energy carbonyl-rich covalent organic polymers for energy storage.
