Electric Literature of 254-60-4, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 254-60-4, 1,8-Diazanaphthalene, introducing its new discovery.

We report the bonding strength of nickel ions in trinickel extended metal atom chains (EMACs) and dinickel complexes using Raman, surface-enhanced Raman scattering (SERS), and electrochemical SERS (ECSERS). By using the redox ability of gold and silver nanoparticles during plasmonic excitation, the bonding strength and the valence state of metal ions can be determined. For dinickel complexes, we assign the Raman band at 322 cm-1 to Ni2+-Ni3+ stretch in [Ni2(TPG)4]BF4 (TPG = N,N?,N?-triphenylguanidinate, [Ni2]5+) and 327 cm-1 for Ni2+-Ni1+ stretch of [Ni2]3+ moieties in Ni5(camnpda)4. For trinickel EMACs, no band is assigned to Ni3 symmetric stretch nuNi3 sym in the neutral form Ni3(dpa)4X2 (dpa = dipyridyl amido and X = NCS, Cl). In the reduced form, the ECSERS curves show the band at 242 cm-1, which also appeared at gold nanoparticle SERS measurement, assigned to nuNi3 sym for [Ni3]5+ core. The trinickel complexes were reduced by gold nanosphere, and this nuNi3 sym band is further enhanced with SERS measurements when gold nanorods were used and the trinickel EMACs served as bridging compounds on both ends. On increasing the applied voltage in ECSERS to +1.3 V, complexes were oxidized and one additional band at 351 cm-1 appeared. This new band is assigned to nuNi3 sym of [Ni3]7+ in [Ni3(dpa)4X2]+. Great vibrational frequency indicates that one electron from the metal sigma? orbital instead of ligand was removed, leading to a three metal center bond. Distinct from the vibrational band wavenumber obtained in dinickel complexes, we confirm that [Ni3]5+,7+ has delocalized electronic structures.

Nucleobase recognition in water is successfully achieved by the use of an abasic site (AP site) as the molecular recognition field. We intentionally construct the AP site in DNA duplex so as to orient the AP site toward a target nucleobase and examine the complexation of 2-amino-7-methylnaphthyridine (AMND) with nucleobases at the AP site. AMND is found to selectively bind to cytosine (C) base with a 1:1 binding constant of >106 M-1, accompanied by remarkable quenching of its fluorescence. In addition to hydrogen bonding, a stacking interaction with nucleobases flanking the AP site seems responsible for the binding properties of AMND at the AP site. Possible use of AMND is also presented for selective and visible detection of a single-base alternation related to the cytosine base. Copyright

The electrostatic nature of the hydrogen bond makes it straightforward, in principle, to electrochemically perturb the strength of hydrogen bonds by using oxidation to create stronger H-donors or reduction to create stronger H-acceptors. However, oxidation or reduction can also lead to proton transfer and subsequent electron transfer, which can nullify the effect of the initial electron transfer. Illustrative examples of these complications based on a series of investigations of electroactive, urea-containing 2 H-bond dimers are described. It is also shown that proton transfer accompanying electron transfer can be used to advantage with two examples of oxidative dissociation of 4 H-bond dimers that are of interest for the construction of supramolecular polymers and gels. In both cases proton transfer is key to achieving the desired outcome. Moving forward, it is argued that proton transfer should always be considered as a possible useful component in the design of electrochemically controllable H-bonding systems.
