Highly Efficient Electron-Transporting/Injecting and Thermally Stable Naphthyridines for Organic Electrophosphorescent Devices

A series of 1,8-naphthyridine derivatives is synthesized and their electron-transporting/injecting (ET/EI) properties are investigated via a multilayered electrophosphorescent organic light-emitting device (OLED) using fac-tris(2-phenylpyridine)iridium [Ir(ppy)3] as a green phosphorescent emitter doped into a 4,4-N,N-dicarbazolebiphenyl (CBP) host with 4,4-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (a-NPD) as the hole-transporting layer, and poly(arylene ether sulfone) containing tetraphenylbenzidine (TPDPES) doped with tris(4-bromophenyl)ammonium hexachloroantimonate (TBPAH) as the hole-injecting layer. The turn-on voltage of the device is 2.5 V using 2,7-bis[3-(2-phenyl)-1,8-naphthyridinyl]-9,9-dimethylfluorene (DNPF), lower than that of 3.0 V for the device using a conventional ET material. The maximum current efficiency (CE) and power efficiency (PE) of the DNPF device are much higher than those of a conventional device. With the aid of a hole-blocking (HB) and exciton-blocking layer of bathocuproine (BCP), 13.213.7% of the maximum external quantum efficiency (EQE) and a maximum PE of 50.254.5 lm W1 are obtained using the naphthyridine derivatives; these values are comparable with or even higher than the 13.6% for conventional ET material. The naphthyridine derivatives show high thermal stabilities, glass-transition temperatures much higher than that of aluminum(III) bis(2-methyl-8-quinolinato)-4-phenylphenolate (BAlq), and decomposition temperatures of 510518 degrees C, comparable to or even higher than those of Alq3.

Benzo[c][2,7]naphthyridine-2-yl-, 5-yl- and 2,5-diyl novaldiamines – synthesis and investigation of anti-malarial activity

The 2,5-dichlorobenzo[c][2,7]naphthyridine 6 was synthesized starting from the 2-pyridone 1 in four or five steps, respectively. The 5-yl amine 7 and the 2,5-diyl amines 8 and 9 were isolated by the reaction of compound 6 with the novaldiamine base. Starting with the reaction of the 6-chloropyridine 3 with the novaldiamine base to yield the 6-aminopyridine 11, the 2-yl amine 13, isomeric to 7, was obtained. Compounds 7-13 were tested for in vitro antimalarial activity using a chloroquine sensitive and resistant Plasmodium falciparum strain. The highest activity was shown by 8 with IC50 values of 90 nM and 190 nM, respectively.

Better Sensing through Stacking: The Role of Non-Covalent Interactions in Guanine-Binding Sensors

A series of aryl-substituted naphthyridine-based sensors for 9-alkylguanine was analyzed using density functional theory and correlated ab initio methods. First, the 2-acetamido-1,8-naphthyridine backbone of these sensors was examined with rigorous ab initio methods and was shown to exhibit a guanine-binding energy commensurate with that of cytosine. Second, computational analyses of a guanine-specific fluorescent sensor from Fang and co-workers (Org. Lett. 2016, 18, 1724) resulted in a revised binding model and showed that p-stacking interactions with a pendant pyrenyl group are vital for strong guanine binding. Finally, 24 related guanine sensors with varying aryl groups were studied. Overall, it was found that both the geometry and the point of attachment of the pendant aryl groups significantly impact the guanine-binding affinity. This occurs through both the direct modulation of the pi-stacking interactions with guanine and the secondary geometric effects that influence the strength and number of hydrogen bonds between guanine and the ethylenediamine linker connecting the arene to the naphthyridine backbone.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 5959-52-4 is helpful to your research. Quality Control of 3-Amino-2-naphthoic acid.

SYNTHESIS, DNA BINDING, AND CLEAVAGE STUDIES OF Co(III) COMPLEXES WITH FUSED AROMATIC NO/NN-CONTAINING LIGANDS

Four new Co(III) complexes, namely [Co(ca)(3)](PF6)(3), [Co(phen)(2)(cq)](PF6)(3), [Co(bnp)(3)] (PF6)(3), and [Co(phen)(2)(bnp)](PF6)(3) (where cq = chromeno[2,3-b]quinoline, phen = 1,10-phenanthroline and bnp = dibenzo[b,g][1,8]naphthyridine), were synthesized and structurally characterized. Spectroscopic data suggested an octahedral geometry for all the complexes. Binding studies of these complexes with double-stranded (dc)DNA were analyzed by absorption spectra, viscosity, and thermal denaturation studies. The mulls revealed that the metal complex intercalates into the DNA base stack as intercalator. The oxidative cleavage activities of the complexes were studied with supercoiled pUC19 DNA using gel electrophoresis and the results show that the complexes have potent nuclease activity.

A Defective Linear Pentachromium Complex for the Enhanced Catalysis of the Cycloaddition of CO2 with Propylene Oxide

Based on the ligand (2,7-bis(alpha-pyrimidylamino)-1,8-naphthyridine (H(2)bpmany)), a linear pentachromium complex [Cr-5(mu(5)-bpmany)(4)Cl-2]PF6(1, mu(5)-bpmany = 2,7-bis(a-pyrimidylamino)-1,8-naphthyridine) was synthesized. The crystal structure of compound 1 has been characterized by X-ray crystallography. Interestingly, one metal atom in the center is missing in this linear chain, leading to the defective pentachromium metal string structure which is similar with the reported complex [Cr-5(mu(5)-dpznda)(4)Cl-2] (2, dpznda = N-2,N-7-di(pyrazin-2-yl)-1,8-naphthyridine-2,7-diamine). The central Cr(III) ion of 1 is eight-coordinated and is also rare in the chromium complex. The reaction of carbon dioxide with propylene oxide that generates propylene carbonate (PC) when catalyzed by [Cr-5(mu(5)-bpmany)(4)Cl-2]PF6 was investigated. Different reaction conditions including temperature and pressure were studied to optimize the reaction conditions.
