Electrochemical behavior of a Rh (pentamethylcyclopentadienyl) complex bearing an NAD(+)/NADH-functionalized ligand

A RhCp* (Cp* = pentamethylcyclopentadienyl) complex bearing an NAD(+)/NADH-functionalized ligand, [RhCp*(pbn)Cl]Cl ([1] Cl, pbn = (2-(2-pyridyl) benzo[b]-1,5-naphthyridine)), was synthesized. The cyclic voltammogram of [1]Cl in CH3CN shows two reversible redox waves at E-1/2 = -0.58 and -1.53 V (vs. the saturated calomel electrode (SCE)), which correspond to the Rh-III/Rh-I and pbn/pbn(center dot-) redox couples, respectively. The addition of acetic acid to the solution afforded the proton-coupled two-electron reduction of [1]Cl at -0.62 V, from which [RhCp*(pbnHH)Cl](+) was selectively generated, probably via a hydride transfer from a Rh-III-hydride intermediate to the pbn ligand. Complex [1]Cl is stable under acidic conditions, whereas a methyl proton of the Cp* moiety dissociates under basic conditions. The resulting anionic methylene group attacks the para carbon of the free pyridine of pbn, accompanied by protonation of the nitrogen atom of the ligand. As a result, treatment of [1]Cl with a base produces selectively the cyclic complex [1CH]Cl, which bears a reduced pbn framework (pbnCH). [1CH]Cl forms 1 : 1 adducts with PhCOO-via hydrogen bonding. A similar adduct, formed by a Ru-pbnHH scaffold and RCOO-(R = CH3, C6H5), has been reported to react with CO2 to produce HCOO-under concomitant regeneration of Ru-pbn. The adduct of [1CH]Cl with PhCOO-, however, lacks such hydride-donor ability, due to a steric barrier in the molecular structure of [1CH]Cl, which hampers the hydride transfer.

Synthesis of Naphthyridine Dimers with Conformational Restriction and Binding to DNA and RNA

One of the important determinants in the efficiency of a molecular interaction is the necessity for conformational changes in host and/or guest molecules upon binding. In small-molecule interactions with nucleic acids, conformational changes on both molecules are often involved, especially in intercalating binding. Mismatch binding ligands (MBLs) we described here consist of two heterocycles that predominantly exist in one conformation, so it is of interest to determine if such molecules can bind to any DNA and RNA structures. One molecule, 1-NHR, which predominantly exists as the unstacked conformation in aqueous solvent, has been successfully synthesized and characterized. Compound 1-NHR did not efficiently bind to GX/Y DNA and RNA sequences, but the binding pattern is different from that of authentic MBL naphthyridine carbamate dimer. In vitro selection of RNA that specifically binds to 1-NHR was performed from pre-miR-29a loop library RNA, and one RNA, to which 1-NHR bound with high affinity, has been successfully identified. Although it was anticipated that 1-NHR, with a predominantly unstacked conformation, would show entropy-driven binding, isothermal titration calorimetry analysis suggested that the binding of 1-NHR to RNA was enthalpy driven with an apparent K-d of about 100nm.

1,5-Naphthyridine-based conjugated polymers as co-sensitizers for dye-sensitized solar cells

1,5-naphthyridine-based conjugated polymers (P1 and P2) were synthesized and extensively characterized by H-1 NMR, thermogravimetric analysis (TGA), FT-IR. These polymers were employed as co-sensitizers in DSSCs sensitized with Ru (II) based N3 dye. In comparison to the N3 sensitized device, the P1 and P2 co-sensitized solar cells demonstrated enhanced open circuit voltage, (V-OC) of 825 and 788 mV and better fill factor (FF) of 59 and 58%, respectively. The co-sensitization of P1 and P2 with N3 increased the overall efficiencies to 5.88% and 6.21%, respectively, as compared to 5.58% for N3 sensitizer alone. The fabricated device based on N3 co-sensitized with P2 displayed higher charge recombination resistances as compared to the devices based on N3 alone or N3 co-sensitized with P1. The conjugated polymers are believed to enhance light harvesting ability and reduce the charged recombination in the co-sensitized solar cells.

Construction of new heteroacenes based on benzo[b]thieno[2,3-d] thiophene / quinoline or 1,8-naphthyridine systems using the Friedlander reaction

Two new classes of heteroacenes, namely benzo[4′,5′]thieno[2′,3′:4,5]thieno[3,2-b]quinolines and benzo [4′,5′]thieno[2′,3′:4,5]thieno[3,2-b][1,8]naphthyridines, have been formed using the Friedlander reaction to annulate the benzo[b]thieno[2,3-d]thiophene scaffold to quinoline or 1,8-naphthyridine fragments. In accordance with this synthetic strategy, benzo[b]thieno[2,3-d]thiophen-3(2H)-ones were treated with 2-aminobenzaldehydes or 2-aminonicotinaldehyde in the presence of pyrrolidine in glacial acetic acid at reflux to give the desired quinoline- or 1,8-naphthyridine-fused compounds, respectively. The optical and electrochemical properties of selected heteroacenes were determined. (C) 2019 Elsevier Ltd. All rights reserved.
