Radiosensitizers are drugs that make cancer cells more sensitive to radiation therapy. The cytotoxic properties of such compounds due the fact in cell these undergo one-electron reduction generate radical anions. Therefore, their theoretical and/or experimental study is high interest. To determine correlation between potential determined by cyclic voltammetry measurements and some physicochemical selected radiosensitizers calculations electron affinities based on DFT method with B3LYP...
This study explains the controversies in literature concerning number of electrons involved oxidation quercetin. stems from inappropriate handling samples, which require strict anaerobic conditions. The redox potential quercetin strongly depends on pH and presence dissociation forms solution.
Single-molecule conductance in a series of extended viologen molecules was measured at room temperature using gold-molecule-gold scanning tunneling microscopy break junction arrangement. Conductance values for individual change from 4.8 ± 1.2 nS the shortest compound to 2.9 1.0 with six repeating units and length 11 nm. The latter value is almost 3 orders magnitude higher than that reported all-carbon-based aromatic molecular wires comparable length. On basis molecules, an attenuation factor...
Charge transport characteristics of asymmetric molecules containing a 9,9′-spirobifluorene platform coupled covalently to phenylene ethynylene linker capped with either thiol or nitrile end group are investigated by break junction techniques. It is shown that the provides very good electronic coupling metallic leads and differences in charge depend solely on type anchoring at opposite molecule. The SH-terminated molecule has 1 order magnitude higher conductance compared CN-terminated one,...
Abstract Properties of the Eu III /Eu II redox couple, in presence one a group different ligands ligands, were investigated using several electrochemical methods. Ligands used this study included cyclodextrins, polyazamacrocycles and poly(aminocarboxylates). The poly(aminocarboxylate) containing currently as MRI contrast agents (DTPA, DOTA) well newly developed [1,4‐DOTA(GAC 12 ) 2 , 1,7‐DOTA(GAC ] with potential use studied. Cyclic voltammetry, phase sensitive AC DC polarography highly...
Molecular-level multielectron handling toward electrical storage is a worthwhile approach to solar energy harvesting. Here, strategy which uses chemical bonds as electron reservoirs introduced demonstrate the new concept of "structronics" (a neologism derived from "structure" and "electronics"). Through this concept, we establish, synthesize, thoroughly study two multicomponent "super-electrophores": 1,8-dipyridyliumnaphthalene, 2, its N,N-bridged cyclophane-like analogue, 3. Within both...
The forces required for the detachment of ferrocene (Fc) from β-cyclodextrin (βCD) in a single host (βCD)-guest complex were investigated using force spectroscopy under electrochemical conditions. redox state guest Fc moiety as well structure supporting matrix was found to decisively affect nanomechanical properties complex.
