Fourteen new derivatives of 9,10-anthraquinone or 9,10-dimethoxyanthracene were designed, synthesised and characterised. Regarding the structure, the compounds are π-conjugated (cross and linear, respectively) and feature thiophene terminated side arms attached to five different positions of the anthraquinone or anthracene core. The synthesis of the compounds involves a cross-coupling procedure in the key reaction steps. Crystal structures of compounds 5 and 19 have been studied. The thiophene containing title compounds 1-5 can be reduced and oxidised by a two step redox process. The electrochemical parameters have been analysed by cyclic voltammetry (CV). Theoretical calculations in the framework of all-electron density functional theory (DFT) were used to investigate the electronic structure of the individual free molecules. Furthermore, calculations of the transport properties of model devices containing compounds 1-3 and respective reduced hydroquinone derivatives assembled at Au(111) electrodes were carried out to evaluate their potential for the application as redox-active switches.

The synthesis of a 2′-deoxyuridine nucleoside linked to an anthraquinone moiety, and its incorporation into oligonucleotides are described, including a facile oxidative demethylation with phenyliodine(iii) bis(trifluoroacetate) to reveal the anthraquinone motif. Furthermore, some useful physical and electrochemical properties of the obtained oligonucleotide are also reported, which allow its principal use in electrochemical DNA assays.

Our purpose is to develop a nitroxide-based ESR probe for singlet oxygen.Among the new anthracenyl nitroxides 1-4 prepared, nitroxide 1 is the most useful. 1 reacts with singlet oxygen to give endoperoxide 18 quantitatively in organic solvents as well as when 1 is incorporated in the bilayers of DMPC vesicles.The reaction is sufficiently rapid an the resulting changes in the ESR spectra are sufficiently characteristic so that the conversion of 1 into 18 may serve as an ESR-based probe for singlet oxygen.
