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.

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.

Association of phenyldiboronic acids with hydrogen bond acceptors to form hydrogen bonded DD.AA-type complexes: a DFT study

Boronic acid is known to form DD.AA, DA.AD, and AA.DD type complexes. In this article, the ability of phenyldiboronic acid to associate with hydrogen bond acceptors (1,8-naphthyridine, 5,6,11,12-tetraazanaphthacene, 2,8a-dihydropyrano[2,3-b]pyran and 4aH-[1,4]dioxino[2,3-b][ 1,4] dioxine) has been analyzed in light of density functional theory. Stabilization energy and thermochemical analysis predict the feasibility of formation of DD.AA type complexes between phenyldiboronic acid and N-/O-hydrogen bond acceptors. The gas and solvent phase calculations showed that the stabilization energy varies with the size of the association geometry. IR and NMR studies revealed the weakening of the O-H bond during complexation. Complexes with as many as three boronic acids and four hydrogen bond acceptors are studied and are predicted to be stable.

Zinc(II) complexes with aromatic nitrogen-containing heterocycles as antifungal agents: Synergistic activity with clinically used drug nystatin

Three novel Zn(II) complexes, [ZnCl2(qz)(2)] (1), [ZnCl2(1,5-naph)](n) (2) and [ZnCl2(4,7-phen)(2)] (3), where qz is quinazoline, 1,5-naph is 1,5-naphthyridine and 4,7-phen is 4,7-phenanthroline, were synthesized by the reactions of ZnCl2 and the corresponding N-heterocyclic ligand in 1:2 molar ratio in ethanol at ambient temperature. The characterization of these complexes was done by NMR, IR and UV-Vis spectroscopy, and their crystal structures were determined by single-crystal X-ray diffraction analysis. Complexes 1 and 3 are mononuclear species, in which Zn(II) ion is tetrahedrally coordinated by two nitrogen atoms belonging to two qz or 4,7-phen ligands, respectively, and by two chloride anions, while complex 2 is a 1D coordination polymer that contains 1,5-naph as bridging ligand between two metal ions. In agar disc-diffusion assay, complexes 1-3 manifested good inhibitory activity against two investigated Candida strains (C. albicans and C. parapsilosis), while not inducing toxic effects on the healthy human fibroblast cell line (MRC-5). This activity was not fungicidal, as revealed by the broth microdilution assay, however complex 3 showed the ability to modulate Candida hyphae formation, which is an important process during infection and showed significant synergistic effect with clinically used antifungal polyene nystatin.
