A ruthenium(II) complex bearing a naphthyridine-functionalized pyrazole ligand catalyzes oxidant free and acceptorless selective double dehydrogenation of primary amines to nitriles at moderate temperature. The role of the proton-responsive entity on the ligand scaffold is demonstrated by control experiments, including the use of a N-methylated pyrazole analogue.

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.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, spectroscopic, and theoretical assessments of solvent structures and their interactions with reaction intermediates. 126-30-7, Name is 2,2-Dimethylpropane-1,3-diol, SMILES is OCC(C)(C)CO, belongs to naphthyridine compound.

Highly crystalline conjugated polymers represent a key material for producing high-performance thick-active-layer polymer solar cells (PSCs). However, despite their potential, a limited number of crystalline polymers are used in PSCs because of the lack of highly coplanar acceptor building blocks and insufficient light absorptivity ( < 10(5)) of most donor (D)-acceptor (A)-type polymers. This study reports a series of novel 3,7-di(thiophen-2-yl)-1,5-naphthyridine-2,6-dione (NTDT) acceptor-based conjugated polymers, PNTDT-2T, PNTDT-TT, and PNTDT-2F2T, synthesized with 2,2-bithiophene (2T), thieno[3,2-b]thiophene (TT), and 3,3-difluoro-2,2-bithiophene (2F2T) donor units, respectively. PNTDT-2F2T exhibits superior polymer crystallinity and a much higher absorption coefficient than those of PNTDT-2T or PNTDT-TT because of adequate matching between highly coplanar A (NTDT) and D (2F2T) building blocks. A bulk heterojunction solar cell based on PNTDT-2F2T exhibits a power conversion efficiency of up to 9.63%, with a high short circuit current of 18.80 mA cm(-2) and fill factor of 0.70, when a thick active layer (>200 nm) is used, without postfabrication hot processing. The findings demonstrate that the polymer crystallinity and absorption coefficient can be effectively controlled by selecting appropriate D and A building blocks, and that NTDT is a novel and versatile A building block for highly efficient thick-active-layer PSCs.

The influence of three naphthyridines (NTDs) on acidic dissolution of mild steel was evaluated using experimental methods. Protection abilities of the NTDs molecules are increases with their concentrations. Maximum inhibition efficiency of 98.69% was observed for NTD-3 molecule at its 4.11×10(-5) mol/L-1 concentration. The inhibition efficiencies of NTDs molecules followed the order: NTD-1 (96.1%) < NTD-2 (97.4%) < NTD-3 (98.7%). Polarization study showed that NTDs acted as mixed type inhibitors and they preferably block the active sites accountable for the corrosion. EIS study suggested that the NTDs inhibit corrosion because of their adsorption at electrolyte/metal interfaces and their adsorption followed Langmuir adsorption isotherm. AFM analysis was adopted to support the adsorption inhibitive behavior of NTDs.

New lanthanide complex Gd-ANAMD containing 2-amino-7-methyl-1,8-naphthyridine was achieved for selective magnetic resonance imaging towards guanosine 5′-monophosphate over other ribonucleotide polyphosphates in aqueous media and in vivo. The formation of strong multi-hydrogen bonds between naphthyridine and guanosine made the phosphate in guanosine 5′-monophosphate positioned on a suitable site to coordinate with the lanthanide ion. The substitution of the coordination naphthyridine by the phosphate oxygen atoms caused obvious relaxivity decrease. The negligible cytotoxicity and appropriate blood circulation time of Gd-ANAMD allow potential application of Magnetic Resonance Imaging in vivo. H-1 NMR confirmed that the selectivity of these lanthanide complexes towards guanosine was attributed to the formation of hydrogen bonds between the guanine moeity and the naphthyridine. The fluorescence detection and lifetime measurement of Tb-ANAMD and Eu-ANAMD suggested that the decrease of the relaxivity is not attributed to the change of the q value, but caused by the prolonging of the residence lifetime of inner-sphere water.
