Expandable porous organic frameworks with built-in amino and hydroxyl functions for CO2 and CH4 capture

The synthesis of porous organic 3D frameworks, wherein amine, hydroxyl and Li-alkoxide functions were built directly on the monomer-unit carbon core, realizes improved interactions with target gases. CO2 was retained by the amine group with a r

Immobilization of an Iridium Pincer Complex in a Microporous Polymer for Application in Room-Temperature Gas Phase Catalysis

An iridium dihydride pincer complex [IrH2(POCOP)] is immobilized in a hydroxy-functionalized microporous polymer network using the concepts of surface organometallic chemistry. The introduction of this novel, truly innocent support with remote OH-groups enables the formation of isolated active metal sites embedded in a chemically robust and highly inert environment. The catalyst maintained high porosity and without prior activation exhibited efficacy in the gas phase hydrogenation of ethene and propene at room temperature and low pressure. The catalyst can be recycled for at least four times.

Methane-perylene diimide-based small molecule acceptors for high efficiency non-fullerene organic solar cells

We report perylene diimide (PDI) small molecules based on diphenylmethane, triphenylmethane, and tetraphenylmethane cores, named PM-PDI2, PM-PDI3 and PM-PDI4, respectively. The OSC performances of PM-PDI3 and PM-PDI4 are comparable. The PM-PDI3 based device with PDBT-T1 as the donor achieved a highest power conversion efficiency (PCE) of 7.58% along with a high open-circuit voltage (VOC) of 0.98 V, a short-circuit current density (JSC) of 11.02 mA cm-2 and a high fill factor (FF) of 69.9%, a 1.32 times boost in PCE with respect to the PM-PDI2 based control device (3.26%). The high photovoltaic performance of the PM-PDI3 based device can be attributed to its relatively high-lying LUMO level, complementary absorption spectra with the polymer donor material PDBT-T1, relatively favorable morphology and improved exciton dissociation and charge collection efficiency. A PCE of 7.58% is among the highest efficiency of phenyl-methane as core based non-fullerene organic solar cells. Overall, this work provides a new approach to enhance the performance of non-fullerene acceptors.

Internal functionalization of three-dimensional covalent organic frameworks

Thinking inside the COF: Internally functionalized, boroxine-linked, three-dimensional, covalent organic frameworks (COFs) can be synthesized by co-crystallizing a truncated, trifunctional monomer with the parent tetrafunctional building block. The functionalized COFs possess accessible functional groups and a distinct interior microenvironment. In the picture the orange sphere corresponds to an alkyl chain or an allyl group in the pore interior.
