We have studied the structural and photophysical characteristics of a series of 1,8-naphthyridine-BF2 compounds in detail. The purpose of quantum-chemical calculations is to study the effect of electron-withdrawing (electron-donating) substituents and core-frame conjugation on the optical properties. The solvent effects are researched in toluene, CH2Cl2, THF, acetone, CH3CN and CH3OH solutions, respectively, by polarizable continuum model (PCM). The results show that the HOMO, LUMO, energy gaps, IP and EA of BF2 core compounds 1-3 containing 1,8-naphthyridine change regularly due to the different degrees of conjugation framework. However, the influence of the substituent changes on these molecules is not significant. The results also show that the maximum absorption wavelengths of the complexes exhibit blue shift as the polarity of the solvent increases from toluene to CH3OH. In addition, the absorption wavelengths of the studied molecules are red-shifted to some extent due to the increased conjugation in the central framework. All calculations reveal that the naphthyridine-BF2 compounds are expected to be a useful luminescent material for OLEDs.

Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. Application In Synthesis of Dibenzo[b,d]furan, The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 132-64-9, Name is Dibenzo[b,d]furan, SMILES is C12=CC=CC=C1C3=CC=CC=C3O2, belongs to naphthyridine compound. In a article, author is Dhamodharan, V., introduce new discover of the category.

Various biologically relevant G-quadruplex DNA structures offer a platform for therapeutic intervention for altering the gene expression or by halting the function of proteins associated with telomeres. One of the prominent strategies to explore the therapeutic potential of quadruplex DNA structures is by stabilizing them with small molecule ligands. Here we report the synthesis of bisquinolinium and bispyridinium derivatives of 1,8-naphthyridine and their interaction with human telomeric DNA and promoter G-quadruplex forming DNAs. The interactions of ligands with quadruplex forming DNAs were studied by various biophysical, biochemical, and computational methods. Results indicated that bisquinolinium ligands bind tightly and selectively to quadruplex DNAs at low ligand concentration (similar to 0.2-0.4 mu M). Furthermore, thermal melting studies revealed that ligands imparted higher stabilization for quadruplex DNA (an increase in the T-m of up to 21 degrees C for human telomeric G-quadruplex DNA and >25 degrees C for promoter G-quadruplex DNAs) than duplex DNA (Delta T-m < 1.6 degrees C). Molecular dynamics simulations revealed that the end-stacking binding mode was favored for ligands with low binding free energy. Taken together, the results indicate that the naphthyridine-based ligands with quinolinium and pyridinium side chains form a promising class of quadruplex DNA stabilizing agents having high selectivity for quadruplex DNA structures over duplex DNA structures. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states.

Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. In an article, author is Hussain, Aftab, once mentioned the application of 132-64-9, Name is Dibenzo[b,d]furan, molecular formula is C12H8O. Now introduce a scientific discovery about this category, Related Products of 132-64-9.

A series of derivatives based on 10,10-dimethyl-5,10-dihydro-pyrido[4,3-b][1,6] naphthyridine-diphenylsulphone (DMDHNP-DPS) named 1a was designed with CH/ N and H/ CN substitution at the DPS acceptor unit to obtain blue thermally activated delayed fluorescence (TADF) materials. The parent molecule 1a was chosen from our previous report after CH/ N substitution at the DMAC donor fragment. The highest occupied molecular orbitals (HOMOs) and the lowest unoccupied molecular orbitals (LUMOs) were largely distributed over the DMDHNP donor and DPS acceptor units, respectively, resulting in a slight overlap between the HOMO-LUMO and hence a smaller singlet-triplet energy gap (DEST). Steric hindrance caused a large dihedral angle (E821-891) between the plane of the electrondonating DMDHNP unit and the electron-accepting DPS unit in the substituted derivatives. Calculated results indicated that the DEST values of H/ CN substituted derivatives were smaller than those of the corresponding CH/ N derivatives which were favorable for the reverse intersystem crossing (RISC) process from the lowest excited triplet states (T1) to the lowest excited singlet (S1) states and ultimately to the ground state (S0) causing delayed emission. The emission wavelengths (lem) of all the designed molecules were found to be in the range of 397-497 nm. The incorporation of the -NQatom or the -CN group at the ortho and meta positions of DPA reduced the transition energies from LUMO -HOMO in the S1 states, resulting in a red-shift. Moreover, the lem values displayed a more substantial bathochromic-shift as the number of -NQatoms or -CN groups increased. The two of the designed molecules (1h and 1i) showed sky-blue emission (494 nm and 497 nm), and the four of the investigated compounds (1c, 1d, 1f, and 1g) displayed blue emission (416 nm, 447 nm, 437 nm, and 432 nm, respectively) indicating that these investigated derivatives were efficient sky-blue to blue TADF candidates. Among all the investigated derivatives, the smaller DEST values for the designed systems 1f (0.03 eV) and 1g (0.02 eV) and appropriate lem values of 437 nm and 432 nm make them excellent candidates for blue TADF materials. Our theoretical investigation might offer hints for the construction of efficient blue TADF-based organic light emitting diodes (OLEDs) in the future.

A novel series of heterocyclic systems fused coumarins and chromones were efficiently synthesized from chemical transformations of 6,8-dimethylchromone-3-carbonitrile (1) with a variety of carbon nucleophilic reagents. Ring opening ring closure reactions of carbonitrile 1 with cyanoacetohydrazide, malononitrile dimer (2-aminoprop-1-ene-1,1,3-tricarbonitrile), and isomeric cyclohexanediones led to a diversity of coumarins and chromones fused nitrogen heterocyclic systems.

DNA molecular glue is a small synthetic ligand that can adhere two single-stranded DNAs that do not spontaneously hybridize with each other. For reversible control of DNA hybridization by an external light stimulus, we have developed a photoswitchable molecular glue for DNA. The photoswitchable molecular glue, NCDA, consists of two guanine-recognizing naphthyridine moieties connected with a photochromic azobenzene unit. Azobenzene undergoes a reversible cis/trans isomerization by photoirradiation, which changes the relative orientations and positions of the naphthyridine moieties, resulting into photoswitching of NCDA binding to the DNA containing GG-mismatch. NCDA in the cis configuration binds to a GG-mismatch sequence and induces the formation of the DNA duplex. Using the photoswitchable binding property of NCDA, the hybridization event of two natural unmodified DNAs can be reversibly controlled by an external light stimulus.

A new asymmetrical photochromic diarylethene has been synthesized by using 1,8-naphthyridine as a functional group and perfluorodiarylethene as photoswitching unit via a peptide bond linkage, and its molecular structure was characterized by single crystal X-ray diffraction analysis. The compound exhibited favorable photochromism upon irradiation with UV/vis light, and its fluorescent behaviour could be efficiently modulated by light, base/acid, and metal ion in THF. The deprotonated derivative of the diarylethene also showed good photochromism, and displayed remarkable turn-on fluorescence response during photocyclization process. Furthermore, the diarylethene was highly selective toward Cd2+ with an obvious fluorescent color change from dark to bright green in THF. Finally, a logic circuit was fabricated with four inputs of the combinational stimuli of UV/vis and Cd2+/EDTA, and one output of fluorescence intensity. (C) 2016 Elsevier Ltd. All rights reserved.

Bicycle ring closure on a mixture of (4aS, 8aR)- and (4aR, 8aS)ethyl 2-oxodecahydro-1,6-naphthyridine-6-carboxylate, followed by conversion of the separated cis and trans isomers to the corresponding thioamide derivatives, gave (4aSR, 8aRS)-ethyl 2-sulfanylidenedecahydro-1,6-naphthyridine-6-carboxylate, C11H18N2O2S.
