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.

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

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.

Synthesis and EPR characterisation of triphenylmethane derivatives carrying N-tert-butyl nitroxide radical moieties: use of the diradical as a ligand for a complex with MnII(hfac)2

Oxidation of the tris(hydroxylamine) 3 with various oxidants has been monitored by EPR spectroscopy and found to show stepwise formation of the corresponding mononitroxide radical 4, dinitroxide radical 5 and trinitroxide radical 6, which was finally conv

The Reduction of Fluorine-containing Triarylmethanols by Formic Acid

Triarylmethanols containing one or more fluorine substituents in the para-positions are converted by 90 percent formic acid into a mixture of the fluorine-containing triarylmethane, and a second component in which one fluorine has been replaced by a hydro
