Hybrid materials are increasingly demonstrating their utility across several optical, electrical, and magnetic applications. Cu(I) halide-based hybrids have attracted attention due to their strong luminescence in the absence of rare-earths. Here, we report three Cu(I) and Ag(I) hybrid iodides with 1,5-naphthyridine and additional triphenylphosphine (Ph3P) ligands. The compounds are built on (Cu/Ag)-I staircase chains or on a rhomboid Cu2I2 dimer and display intense and tunable luminescence. Replacing Cu with Ag, and adding the second kind of organic ligand (Ph3P) tunes the emission color from red to yellow and results in significantly enhanced quantum yield. Density functional theory-based electronic structure calculations reveal the separate effects of the inorganic module and organic ligand on the electronic structure, confirming that bandgap, optical absorption, and emission properties of these phosphors can be systemically and deliberately tuned by metal substitution and organic ligands cooperation. The emerging understanding of composition-structure-property relations in this family provides powerful design tools toward new compounds for general lighting applications.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. In my other articles, you can also check out more blogs about 89-63-4. Application In Synthesis of 4-Chloro-2-nitroaniline.

LC-MS-oriented fractionation of the sponge Aaptos suberitoides resulted in the isolation of four heptacyclic alkaloids, aaptodines A-D (1-4), which contain 9,10-dihydrofuro[2,3-f][1,3]oxazolo[5,4-h]-quinolone and 7,8-dihydrocyclopenta[de][1,6]naphthyridine subunits with a spiro carbon atom. The structures were determined on the basis of NMR spectroscopic and single-crystal X-ray diffraction data analysis aided by electronic circular dichroism calculations and Mosher’s method. A biosynthetic pathway for the formation of aaptodines A-D is postulated. Aaptodine D exhibits potent inhibition against osteoclast formation.

Nitropyridylnaphthalene is the central intermediate for the synthesis of naphthonaphthyridine and benzo–carboline. Whereas the Cadogan reaction gives the carboline, transformation of the nitro group to iodo followed by oxidation and cyclization results in an iodonium salt. A twofold Pd-catalyzed amination leads to the naphthyridine.

A new fluorescent functional monomer DMAAN has been designed and synthesized for the first time. The monomer was expected to bind with cytosine via complementary hydrogen bonding under certain experimental conditions. The synthetic procedure of DMAAN is as follows. A suspension of 2,6-diaminopyridine in phosphoric acid was added to acetylacetone. The mixture was warmed for thirty minutes on a steam-bath. Then 2, 4-dimethyl-7-amino-1,8-naphthyridine (DMAN, mp 216-218 degrees C) was obtained. DMAAN was prepared by the reaction of DMAN with acryloyl chloride in chloroform and triethylether mixed solvent. Acryloyl chloride in anhydrous chloroform was added dropwise over 30 minutes with constant stirring at 4 degrees C. The melting point of the final product was 239-241 degrees C. Mass spectrometry and proton NMR were used to confirm the chemical structure of DMAN and DMAAN. The products were also characterized by UV and fluorescence spectrometry.

The present work reports the biological assays between synthetic BF2-naphtyridine complexes and four proteins: human serum albumin (HSA). calf-thymus DNA (CT-DNA), tyrosinase and acetylcholinesterase enzymes via spectroscopic analysis at physiological conditions, combined with molecular docking simulations. The BF2-complexes presented spontaneous and moderate binding ability to HSA through the ground-state association (static fluorescence quenching mechanism). The main binding site is Sudlow’s site I (subdomain IIA) and the binding does not perturb significantly both secondary and surface structure of HSA. Despite BF2-complexes showed good binding ability with HSA, these compounds presented weak intercalative ability with CT-DNA (the most conventional and simple model to preliminary studies), except in the case of 1 h, which suggested that the presence of electronic donor groups in both aromatic ring moieties of BF2-complex structure can increase the intercalative ability for DNA strands. Competitive binding displacement assays in the presence of methyl green and molecular docking calculations indicated that the studied compounds interact preferentially in the major groove of DNA In addition, the assayed compounds presented the ability to activate or inhibit both tyrosinase (the decontrolled activity can induce melanoma carcinoma) or AChE (involved in reactions related to the function of neurotransmitters) enzymes.

1-alkyl aryl-5-amino-4-(cyanoformimidoyl)imidazoles 4 were reacted with malononitrile and 2-amino-1,1,3-propenetricarbonitrile under mild experimental conditions, which led to 5-amino3-(substituted benzyl)-6,7-dicyano-3H-imidazo[4,5-b]pyridines 5 and 6,8-diamino-3-(4-substituted benzyl)-3H-imidazo[4,5-b]-1,8-naphthyridine-7,9-dicarbonitrile 6, respectively, when the reaction was carried out in the absence of a base, or to 5,7-diamino-3-(4-alkyl aryl)-3H-imidazo[4,5-b] pyridine-6-carbonitrile 8, and 6,8,9-triamino-3-(4-substitutedbenzyl)-3H-imidazo[4,5-b]-1,8-naphthyridine-7carbonitrile 10 in the presence of 1,8-diazabicyclo(5.4.0)undec-7-ene (DBU). Both reactions evolved from an adduct formed by nucleophilic attack of the malononitrile anion or 2-amino-1,1,3-propenetricarbonitrile anion to the carbon of the cyanoformimidoyl substituent. In the case of the malononitrile anion, a 5-amino-1-alkyl aryl-4-(1-amino-2,2-dicyanovinyl)imidazole 7 was isolated when this reaction was carried out in the presence of DBU. The structure of compound 7 was confirmed by spectroscopic methods, and cyclized intramolecularly to 8 by heating in ethanol/triethyl amine.
