Small molecule organic semiconductors have well-defined structures and can be used in place of polymers which often show batch-to-batch variation. Many different electron-rich donor and electron-deficient acceptor units have been used to design materials with reduced HOMO-LUMO gaps and improved mobilities. Here we introduce a novel acceptor unit, 1-dodecyl-6-dodecoxynaphthyridine-2-one. This acceptor unit has been used in the synthesis of two novel compounds, with thiophene and 2,1,3-benzothiadiazole (BT) cores. The BT-containing compound shows a narrower HOMO-LUMO gap, broad solid-state absorption and has been applied to organic field-effect transistors, showing a mobility of 0.022 cm(2) V-1 s(-1) after optimisation of devices using self-assembled monolayers.

Dinickel complexes promote stoichiometric Pauson-Khand reactions of enynes and CO (g). However, catalytic turnover is precluded by the strong binding of CO to the Ni-2 active site. This article describes the use of M(CO)(x) reagents as stoichiometric CO precursors in Ni-2-catalyzed carbonylation reactions. As part of these studies, well-defined heterotrinuclear Ni2Fe, Ni2Co, and Ni2Mn carbonyl clusters are synthesized using the [NDI]Ni-2 platform as a template (NDI = naphthyridine-diimine).

Placement of different types of functionalities around the 1,8-naphthyridine motif via simple synthetic methodologies can easily change the hydrogen bonding patterns involving naphthyridine as hydrogen bonding building block. Discrete or polymeric assemblies are observed while the substituents around the naphthyridine nucleus are varied. Water assisted dimeric structure is found in pyridine appended naphthyridine system and all the structures are determined by X-ray crystallographic analysis.

Pressure-induced irreversible chemical reactions of naphthalene, 2,3-naphthyridine (2,3-Nap), and 1,5-naphthyridine (1,5-Nap) were observed after compression (> 16-18 GPa) at room temperature. Regardless of the initial materials, amorphous products in which sp(3) carbon was formed were obtained after the samples were recovered at ambient pressure. The X-ray photoelectron spectroscopy (XPS) of the product from naphthalene indicated that the carbon sp(3)/sp(2) ratio was much lower than that of benzene nanothreads. Nitrogen remained in the amorphous products from 1,5-Nap and 2,3-Nap and bonded to both sp(3) and sp(2) carbons.

The catalytic utility of [RuL1(CO)(2)I-2] (1), containing an annelated pi-conjugated imidazo-naphthyridine-based mesoionic carbene (MIC) ligand (L-1), is evaluated for E-selective alkyne semihydrogenation. The precatalyst 1, in combination with 2 equiv of AgBArF, semihydrogenates a broad range of internal alkynes with molecular hydrogen (5 bar) in water. (E)-Alkenes are accessed in high yields, and a number of reducible functional groups are tolerated. A chelate MIC ligand and two cis carbonyls provide a well-defined platform at the Ru center for hydrogenation and isomerization. The loss of two iodides and the presence of two carbonyls render the Ru center electron deficient and thus the formation of metal vinylidenes with terminal alkynes is avoided. This is leveraged for the semihydrogenation of terminal alkynes by the same catalytic system in isopropyl alcohol. Reaction profile, isomerization, kinetic, and DFT studies reveal initial alkyne hydrogenation to a (Z)-alkene, which further isomerizes to an (E)-alkene via metal-catalyzed Z -> E isomerization.

Background: Naphthyridine scaffold is an important pharmacophore in compounds which have shown various biological activities like antiviral, antimicrobial, anticancer, antiinflammatory and analgesic. This scaffold is also reported to exhibit activity against HIV, HCMV, HSV, HPV and HCV. Antiviral activity displayed by many naphthyridine analogs is in nM range. Only few review articles are available in literature which describe about various biological activities of naphthyridines, but there is no comprehensive compilation particularly for antiviral activities. Objectives: The objective of this review is to compile the literature on anti-viral activities of naphthyridine analogs. Methods: SciFinder, Google Scholar and PubMed database were searched with keyword naphthyridine and the references obtained were further sorted using keywords antihiv, antiviral and virus, separately. References obtained were considered to review the antiviral literature of naphthyridines. Results: Literature search using SciFinder database with different keywords gave several references. Only references of antiviral activities of naphthyridine compounds were reviewed. References to in-silico studies alone or on formulation development or on patents were excluded. Conclusion: This review will be helpful for future researches to design and synthesize naphthyridine analogs with improved antiviral activities.

A novel functional material was developed by immobilizing an Iminodiacetic acid-erbium (Er) complex onto the surface of magnetic spinel CoFe(2)O(4)nanoparticles. The obtained nanocomposite was fully characterized using different analytical techniques such as FT-IR, XRD, SEM, BET, EDX and X-ray atomic mapping analysis. The catalytic activity of this novel material was investigated in the successful synthesis of 1,8-naphthyridine derivativesviaa three component reaction involving 2-aminopyridine, malononitrile and various aryl aldehydes. The reactions ended up with excellent yields in short reaction times. The catalyst was reused seven times in the proposed reaction without appreciable loss of activity.
