Effect of Specific Solute-Solvent Interaction and Electron Donor-Acceptor Substituents of Novel Pyrazolo Naphthyridines on Fluorescence

Heterocyclic orthoaminoaldehyde such as 4-amino-3-(4-phenyl)-1-phenyl-1H-Pyrazolo[3,4-b]pyridine-5-carbaldehyde was synthesized by multistep reactions involving reduction of azido derivative 2 with LAH to yield aminoalcohol 3 and oxidation of it with MnO2 to aminoaldehyde 4.The pyridine ring annulated on to 4 by Friedlander condensation using acetophenones in presence of base to obtained pyrazolo[3,4-h][1,6]naphthyridine 5 in excellent yield. Study of photophysical properties of 5 revealed that the absorption and emission of them depends up on the substituents present on benzene ring in newly annulated pyridine ring.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 5959-52-4, in my other articles.

Naphthyridines part 4: unprecedented synthesis of polyfunctionally substituted benzo[c][2,7]naphthyridines and benzo[c]pyrimido[4,5,6-ij][2,7]naphthyridines with structural analogy to pyrido[4,3,2-mn]acridines present in the marine tetracyclic pyridoacridine alkaloids

An easy, efficient and one-step synthesis of the versatile, hitherto unreported of polyfunctionally substituted benzo[c][2,7]naphthyridines 4a-c is described. The reaction of 4a-c with sodium azide gives the corresponding tetracyclic ring system 6a-c in near quantitative yield, and with phenyl isothiocyanate it gives the corresponding novel 3-alkyl-2-oxo-6-phenyl-5-thioxo-3,4,5,6-tetrahydro-2H-benzo[c]pyrimido[4,5,6-ij][2,7]naphthyridine-1-carbonitriles 8a-c. Refluxing compound 4a, with alkyl amines 9a-d for 2-3 h furnished 3-alkyl-5-alkylamino-4-amino-2-oxo-2,3-dihydrobenzo[c][2,7]naphthyridine-1-carbonitriles 10a-d, as stable crystalline solids. Compounds 10a-d reacted with acetic anhydride and triethyl orthoformate to furnish novel 3,6-dialkyl-2-oxo-3,6-dihydro-2H-benzo[c]-pyrimido[4,5,6-ij][2,7]naphthyridine-1-carbonitriles 13a-c and 14a-c, respectively. Lastly, diazotization of 10a-c afforded the novel tetracyclic ring system 3,6-dialkyl-2-oxo-3,6-dihydro-2H-benzo[c][1,2,3]triazino[4,5,6-ij][2,7]naphthyridine-1-carbonitriles 16a-c.

Optimizing Polymer Solar Cells Using Non-Halogenated Solvent Blends

More environmentally friendly polymer solar cells were constructed using a conjugated polymer, poly (2,5-thiophene-alt-4,9-bis(2-hexyldecyl)-4,9-dihydrodithieno[3,2-c:3 ‘,2 ‘ h][1,5] naphthyridine-5,10-dione, PTNT, as a donor material in combination with PC71BM as an acceptor in a bulk heterojunction device structure. A non-halogenated processing solvent (o-xylene) and solvent additives that are less harmful to the environment such as 1-methoxynaphthalene (MN) and 1-phenylnaphthalene (PN) were used throughout the study as processing solvents. The most widely used halogenated solvent additives (1,8-diiodooctane (DIO) and 1-chloronaphthalene (CN)) were also used for comparison and to understand the effect of the type of solvent additives on the photovoltaic performances. Atomic force microscopy (AFM) was employed to investigate the surface morphology of the films prepared in the presence of the various additives. The best-performing polymer solar cells provided a high open-circuit voltage of 0.9 V, an efficient fill factor of around 70%, and a highest power conversion efficiency (PCE) of over 6% with the use of the eco-friendlier o-xylene/MN solvent systems. Interestingly, the solvent blend which is less harmful and with low environmental impact gave a 20% rise in PCE as compared to an earlier reported device efficiency that was processed from the chlorinated solvent o-dichlorobenzene (o-DCB).

Ultrafast 2,7-Naphthyridine-Based fluorescent probe for detection of thiophenol with a remarkable Stokes shift and its application In vitro and in vivo

2,7-Naphthyridine derivatives were developed as fluorophores for the first time to design two fluorescence probes, AND-DNP and ND-DNP, which can be applied for detecting thiophenol in aqueous media. Comparing with ND-DNP, AND-DNP showed more favorable properties such as lower background, larger Stokes shift, and higher fluorescence quantum yield for detecting thiophenol. Moreover, the experimental results were verified by theoretical calculations. Hence, AND-DNP was selected as the superior fluorescence probe to detect thiophenol because of its high sensitivity and selectivity. Based on the experimental results, AND-DNP showed a remarkably larger Stokes shift (225 nm), faster response speed (30 s) and higher fluorescence enhancement (240-fold) than most other fluorescent probes for thiophenol reported in the literature. For an extended application, AND-DNP was applied to detect thiophenol quantitatively in real water samples. Meanwhile, AND-DNP also detected thiophenol via red emission in living A549 cells and zebrafish. All these results proved AND-DNP’s potential value as an accurate probe for imaging thiophenol in different environments.

A Ruthenium(II) Complex as a Luminescent Probe for DNA Mismatches and Abasic Sites

[Ru(bpy)(2)(BNIQ)](2+) (BNIQ= Benzor[c][1,7]naphthyridine-1-isoquinoline), which incorporates the sterically expansive BNIQ ligand, is a highly selective luminescent probe for DNA mismatches and abasic sites, possessing a 500-fold higher binding affinity toward these destabilized regions relative to well-matched base pairs. As a result of this higher binding affinity, the complex exhibits an enhanced steady-state emission in the presence of DNA duplexes containing a single base mismatch or abasic site IDNAKRu] compared to fully well-matched DNA. Luminescence quenching experiments with Cu(phen)(2)(2+) and [Fe(CN)(6)](3-) implicate binding of the complex to a mismatch from the minor groove via metalloinsertion. The emission response of the complex to different single base mismatches, binding preferentially to the more destabilized mismatches, is also consistent with binding by metalloinsertion. This work shows that high selectivity toward destabilized regions in duplex DNA can be achieved through the rational design of a complex with a sterically expansive aromatic ligand.
