Published in 2018 at "Journal of Materials Science"

DOI: 10.1007/s10853-018-2822-2

Abstract: Among photothermal materials, perylene diimide radical anions were promising organic candidates with intense and characteristic near-infrared (NIR) absorption bands and non-fluorescence. Herein, two isolable and ambient stable bay-substituted perylene diimide radical anion salts, namely DBrPDI… read more here.

Published in 2017 at "Journal of Electroanalytical Chemistry"

DOI: 10.1016/j.jelechem.2017.12.035

Abstract: Abstract The electrochemical carboxylation of a range of substituted benzophenones was studied in 1-butyl-1-methyl-pyrrolidinium bis(trifluoromethylsulfonyl)imide ionic liquid (IL, ([Bmpy][NTf2])). As expected, the aromatic carbonyls exhibited electrochemical reversibility for the first reduction to the radical anion… read more here.

Published in 2020 at "Mendeleev Communications"

DOI: 10.1016/j.mencom.2020.05.001

Abstract: Radical anion salts and coordination complexes of fullerenes, macrocycles and organic dyes obtained by reduction are considered. The reduction transfers an electron to these molecules enabling their participation in magnetic coupling of spins and/or high… read more here.

Published in 2020 at "Organic letters"

DOI: 10.1021/acs.orglett.0c03846

Abstract: A trisulfur-radical-anion (S3̇-)-triggered C(sp2)-H amination of α,β-unsaturated carbonyl derivatives with simple amines has been demonstrated. This protocol provides convenient access to a variety of synthetically valuable N-unprotected and secondary β-enaminones with absolute Z selectivity and… read more here.

Published in 2024 at "ACS catalysis"

DOI: 10.1021/acscatal.4c01645

Abstract: Two conflicting mechanisms have emerged for the direct arylation of allylic C-H bonds enabled by the combined use of thiol and photoredox catalysis. In the original report (Nature, 2015, 519, 74-77), a radical coupling step-between… read more here.

Published in 2021 at "Journal of the American Chemical Society"

DOI: 10.1021/jacs.1c09595

Abstract: π-Conjugated polymers can serve as active layers in flexible and lightweight electronics and are conventionally synthesized by transition-metal-mediated polycondensation at elevated temperatures. We recently reported a photopolymerization of electron-deficient heteroaryl Grignard monomers that enables the… read more here.

Published in 2019 at "Journal of the American Chemical Society"

DOI: 10.1021/jacs.9b08926

Abstract: Organic radicals are of importance in developing smart materials that have paramagnetic and/or near-infrared optical properties. Their practical applications, however, are limited by the labile nature of the radicals. Here, we demonstrate that by using… read more here.
