A series of neutral nonenzymatic receptors have been synthesized for the recognition of creatinine in a nondegrative way. The receptors contain different heterocyclic moieties for better interactions between host and guest. Among these,1,4, and5are fluorescent receptors for creatinine. From this study, it was found that the receptors1and4containing the naphthyridine moiety have higher binding affinity to the guest creatinine than receptors containing other heterocyclic moiety. Theoretical studies for the calculation of binding energy were carried out using discrete Fourier transform (DFT) for the hosts and their complexation with creatinine in both gas phase and acetonitrile medium.

Different analogs of 1-ethyl-1, 4-dihydro-7-methyH-4-oxo-1, 8-naphthyridine-3-carbohydrazide ( carbonyl hydrazone derivatives of Nalidixic acid, H 1-10) and their copper complexes have been synthesized from reaction of Nalidixic acid hydrazide with substituted benzaldehyde. These are characterized on the basis of IR spectra, H-1-NMR spectra, Mass spectra, elemental and AAS studies for metals. Copper complexes were prepared from CuCl2.2H(2)O and these ligands, the metal ligand ratio was found to be 1:1 and found to be bidentate. The antibacterial, antifungal and antioxidant activities of these hydrazone ligands and their copper complexes have also been evaluated. Copper complexes possess antibacterial and antifungal activities better than the parent hydrazone ligands while they have better antioxidant activity with DPPH radical than copper complexes. Nalidixic acid have maximum of all biological activities, but H-6 showed slightly better antioxidant activity than Nalidixic acid and other activities were close to it.

The pursuit of miniaturization of magnetic electronic components spurs intensive theoretical and experimental researches on designing molecule-scale magnetic devices. Controlling the transport properties is one of the most vital focuses for magnetic molecular devices. In this work, magnetic devices constructed by a single epindolidione (Epi) molecule (5,11-dihydrodibenzo[b,g][1,5]naphthyridine-6,12-dione) bridging two zigzag graphene nanoribbon (zGNR) electrodes are theoretically designed. The Epi molecule can be converted between the keto and enol forms, which is confirmed by first principle molecular dynamics method. The influences of intramolecular proton transfer and the bridging manner between the core molecule and zGNR electrodes on the magnetic transport properties are investigated. Spin-resolved current-voltage (I-V) curves show that both the keto and enol devices display remarkable spin filtering effect. However, the effect of intramolecular proton transfer on the electron transport properties depends on the bridging manner between the Epi molecule and zGNR electrodes. When the Epi molecule is connected to zGNR electrodes with 4,7-sites (A bridging manner), the electron transport properties of molecular junctions are hardly affected by the intramolecular proton transfer. On the contrary, the conductance of the molecular junctions is significantly modulated by the intramolecular proton transfer when the Epi molecule is connected to zGNR electrodes with 4,4′-sites (B bridging manner). Further analysis reveals that the high spin filtering effect originates from stronger coupling between spin-up edge electronic states of zGNR electrodes and states of the core molecule. With B bridging manner, the conjugation characteristics of the Epi molecule as well as the transmission pathway of tunneling electrons can be largely modulated by the intramolecular proton transfer. Our work proposes a feasible way to control the conductance of single-molecule junctions by taking advantage of intramolecular proton transfer.

A Co(OAc)(2)-catalyzed trifluoromethylation and subsequent C(3) -selective arylation of 2-(propargylamino)-pyridines has been developed. A new 6-endo-dig cyclization involving an unprecedented C(3) selective arylation of the pyridines instead of a commonly observed 5-exo-dig cyclization with N is realized. Moreover, the study presents the first case of the installation of a trifluoromethyl group into electron deficient azaarenes. The process delivers an efficient cascade approach to new trifluoromethylated 1,8-naphthyridine structures with a broad substrate scope.

A highly selective colorematric detection of iodie ion based on 1,5-naphthyridine-based conjugated polymers (CPs) is reported. The synthesis of these new conjugated copolymers poly(2-(2-methoxyphenoxy)-6-(3-methoxyphenoxy)-1,5-naphthyridine)-p-bisdodecyloxyphenylene vinylenes) (P1) and poly(2-(2-methoxyphenoxy)-6-(3-methoxyphenoxy)-1,5-naphthyridine)-p-bis-2-(ethyl-hexyloxy)-phenylene vinylenes) (P2) was achieved by the Horner-Emmons polymerization reaction. These polymers were characterized by H-1 NMR, FT-IR and UV-vis spectroscopy and their bandgaps (P1 = 2.35 eV; P2 = 2.25 eV) were determined by cyclic voltammetric measurements. In colorimetric sensing, both these polymers can selectively detect iodide ion in a mixture of water and THE in the presence of a wide range of competing ions including F-, Cl-, Br-, NO3-, CH3COO-, SO4-2, SO3-2, S2O3-2 and CN- and exhibit high sensitivity with LOD of 6.5 and 4.5 ppm, respectively. In the sensing protocol, the addition of aqueous solution of iodide salts to the colorless solution of polymers resulted in bare-eye color change from colorless to yellow, along with concomitant changes in the UV-vis spectra. The time dependent and concentration based studies revealed that P2 was more sensitive and quick in response as compared to P1. (C) 2018 Taiwan Institute of Chemical Engineers.
