Structure-activity relationship (SAR) studies on the mutagenic properties of 2,7-diaminofluorene and 2,7-diaminocarbazole derivatives

We discovered that 2,7-diaminofluorene or 2,7-diaminocarbazole moiety can be employed as a core structure of highly effective NS5A inhibitors that are connected through amide bonds to proline-valine-carbamate motifs. Amide bonds can be easily cleaved via various metabolic pathways upon administration into the body, and metabolites containing 2,7-diaminofluorene and 2,7-diaminocarbazole core structures have been known to be strong mutagens. To avoid the mutagenesis issue of these core structures, we examined various functional groups at the C9 or N9 position of 2,7-diaminofluorene or 2,7-diaminocarbazole, respectively, through the Ames test in TA98 and TA100 mutants of Salmonella typhimurium LT-2. We discovered that, through proper alkyl substitution at the C9 or N9 position, 2,7-diaminofluorene and 2,7-diaminocarbazole moieties can be successfully employed in drug discovery without necessarily causing mutagenicity problems.

Two Anthracene-Based Copolymers as the Hole-Transporting Materials for High-Performance Inverted (p-i-n) Perovskite Solar Cells

Two anthracene-based copolymers, the thiophene-bridged carbazole-anthracene copolymer (abbreviated as PCBZANT) and the thiophene-bridged triphenylamine-anthracene copolymer (abbreviated as PTPAANT), have been developed as the hole-transporting materials (HTMs) for the inverted perovskite solar cells. They were thermally stable with decomposition temperatures of 435 and 420 °C. The High Occupied Molecular Orbitals (HOMO) of -5.15 and -5.24 eV of two copolymers facilitated the hole carriers transfer from the perovskite layer (CH3NH3PbI3, HOMO: -5.4 eV) in contrast to poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS, HOMO: -4.9 eV). The solar cell with PCBZANT (abbreviated as the PCBZANT device) showed the highest power conversion efficiency (PCE) of 15.50%, while the cell with PTPAANT (abbreviated as the PTPAANT device) showed the highest PCE of 14.52%, with increases of 36.2% and 27.6%, respectively, relative to the PEDOT:PSS device. The thorough analysis disclosed that the high performance was mainly ascribed to the enhanced open-circuit voltage (VOC) and short-circuit current density (JSC), being contributed from the efficient hole-carrier extraction, the high hole mobility of two copolymers, and the high-quality perovskite film with large crystal size and less defect. With strong absorption in the range of 350-500 nm, the polymers decreased the destruction of UV-radiation on the perovskite layer as UV-filters and improved the stability of the inverted cells.

Terpyridine-based donor-acceptor metallo-supramolecular polymers with tunable band gaps: Synthesis and characterization

Three new building blocks containing the electron-donor fused-ring motifs carbazole, dithienosilole (DTS) and dithienopyrrole (DTP) and the 2,2′:6′,2″-terpyridine electron-acceptor motif were designed and synthesized. Directed by transition metal ions, the self-assembly of the building blocks triggered polymerization to form the corresponding metallo-supramolecular polymers PCzTPY, PSiTPY and PNTPY, respectively. The UV-vis absorption maxima of the building blocks occur at long wavelengths (351, 368 and 430 nm for CzTPY, SiTPY and NTPY, respectively), which arises from intramolecular charge transfer (ICT) transitions. However, the absorption maxima of their corresponding metallo-supramolecular polymers are clearly red-shifted (to 394, 431 and 509 nm for PCzTPY, PSiTPY and PNTPY, respectively), which is caused by the incorporation of the transition metal ion into the backbones of the target polymers. Based on the above strategies, the resulting metallo-polymers exhibit reduced energy gaps, which are 2.07, 1.97 and 1.56 eV for the PCzTPY, PSiTPY and PNTPY metallo-supramolecular polymers, respectively.
