DNA-Mediated Electrochemistry [PDF]
, 2008 The base pair stack of DNA has been demonstrated as a medium for long-range charge transport chemistry both in solution and at DNA-modified surfaces. This chemistry is exquisitely sensitive to structural perturbations in the base pair stack as occur with

Rapid access to new angular phenothiazine and henoxazine dyes [PDF]
, 2017 The synthesis of some new thiophenyl-derivatized and furanyl-derivatized phenothiazine and phenoxazine dyestuffs is described. This was achieved by two methods after the synthesis of 6-chloro-5H-benzo[a]phenothiazin-5-one, 6-chloro-5H-benzo[a]phenoxazin ...

Wasteful Azo Dyes as a Source of Biologically Active Building Blocks
Frontiers in Bioengineering and Biotechnology, 2021 In this work, an environment-friendly enzymatic strategy was developed for the valorisation of dye-containing wastewaters. We set up biocatalytic processes for the conversion of azo dyes representative of the main classes used in the textile industry ...

Condensed Phenoxazine Dimer and Its Radical Cation [PDF]
Organic Letters, 2020 A condensed phenoxazine dimer was synthesized and characterized. X-ray crystallographic analysis of the dimer shows a double-butterfly structure, in which the nitrogen atoms are located above and below the molecular plane. A radical cation salt of the dimer was obtained using tris(4-bromophenyl)aminium hexafluoroantimonate as the oxidant.

Synthesis, photophysical characterisation and photostability studies of NIR probes with aliphatic, aromatic and chlorinated terminals in 5- and 9-amino positions of benzo[a]phenoxazines [PDF]
, 2016 A new series of benzo[a]phenoxazinium chlorides possessing mono- or disubstituted amines with 3-chloropropyl groups at the 9-position, isopropyl, cyclohexyl and phenyl groups as terminals at 5-postion was synthesised. Photophysical studies were performed

Phenoxazine Based Units- Synthesis, Photophysics and Electrochemistry [PDF]
Journal of Fluorescence, 2010 A few new phenoxazine-based conjugated monomers were synthesized, characterized, and successfully used as semiconducting materials. The phenoxazine-based oligomers have low ionization potentials or high-lying HOMO levels (~4.7 eV), which were estimated from cyclic voltammetry.
