Density Functional Theory Study of Aromatic Adsorption on Iron Surfaces
… ($C_{6}H_{6}$), naphthalene ($C_{8}H_{10}$) and quinolinium ($C_{7}H_{10}N^{+}$) as well as a molecule composed of these fragments known to inhibit acid corrosion on steels used in the oil and gas industry (naphthylmethylquinolinium, $C_{20}H_{16}N^{+}$ or NMQ+). This work represents an effort …

Synthesis and molecular properties of zwitterionic adducts of TCNQ and other related compounds
… of which the methylated Z-~-(N-methyl-4-quinolinium)-a-cyano-4( 2,3,5,6-tetrafluoro)styryldicyanomethanide [CH3(4)Q3CNQF4] is a typical example. Synthetic modification of the donor moiety was also undertaken, resulting in a diverse range of pyridinium, quinolinium and …

Specificity of aldehyde oxidase towards N-heterocyclic cations. Oxidation of quinolinium and related cations by aldehyde oxidase in vitro; the isolation of two products formed simultaneously from a single substrate.
Aldehyde oxidase catalysed oxidation of various quinolinium and related cations has been studied in vitro. Oxidation products were identified by comparison of their spectral and chromatographic characteristics with those of authentic compounds. The N-heterocyclic cations and quinolones used …

The synthesis and characterisation of Langmuir-Blodgett film forming TCNQ adducts.
… of which the short chain Z-beta-(l-butyl-4'-quinolinium)-alpha-cyano-4-styryldicyanomethanide (C[4]H[9](4)Q3CNQ) is a typical example. These zwitterionic D-pi-A materials (where D and A are electron donors and acceptors respectively) exhibit properties such as solvatochromism, molecular …

Optical Studies of Ordered Monomolecular Layers: Ab Initio Simulation and Experiment
… deposited LC molecules. The LB forming molecule quinolinium tricyanoquinodimethanide (Q3CNQ) with long hydrocarbon chain (typically C18H37-Q3CNQ) is chosen. In order to justify the functionality of this material as an alignment layer, the electronic structure and the optical absorptive properties …

Characterization and Synthesis of Cyclodextrin Inclusion Complexes and their Applications as Fluorescent Probes for Sensing Biomacromolecules
… motif was synthesized by covalently linking a quinolinium fluorophore to lithocholic acid (LCA). The CD-based binding motifs and the LCA-based sensing motif self-assemble through host-guest interactions (i.e. 1 binding to LCA displays a Ka = 5.52 × 107 M-1). These inclusion complexes were then …

A study of zwitterionic adducts of TCNQ.
… in detail. The properties of picolinium and quinolinium TCNQ salts are introduced and the extension of this to the molecules studied in this work developed. Two current areas of interest - second harmonic generation and molecular rectification - are then reviewed and the potential …

Induced-Fit Anion Sensing
… the triethylbenzene motif, functionalised with quinolinium groups to sense anions. The receptor binds anions strongly, with complex binding observed, involving a host dimer, 2:1 host:guest and 1:1 host:guest stoichiometries. The receptor functions as a turn-off fluorescence sensor with …
