Understanding the g-tensors of perchlorotriphenylmethyl and Finland-type trityl radicals

Abstract

The 285 GHz EPR spectra of perchlorotriphenylmethyl and tetrathiatriarylmethyl radicals in frozen solution have been accurately measured. The relationship between their molecular structures and their g-tensors has been investigated with...

Perspectives for polychlorinated trityl radicals

“…Most of the current advances have been developed using these types of systems, especially those more soluble in aqueous media, which have been applied for the sensitivity improvement of a wide range of techniques (solid-state NMR, DNP, high field 13 C DNP, EPR). [117][118][119][120][121][122] Therefore, the current trend is to increasingly use DNP techniques in the study of complex biological systems both in vitro and in vivo. Specially promising is the use of DNP in nuclear magnetic resonance imaging (MRI), for example in metabolic imaging applications of 13 C-labelled metabolites in vivo.…”

Synthesis, properties and chemical modification of a persistent triisopropylsilylethynyl substituted tri(9-anthryl)methyl radical

“…However, persistent non-heteroatom-embedded hydrocarbon radicals with small g -anisotropies are the most ideal candidates for use in various spintronic materials. 12 Unfortunately, the library of stable hydrocarbon radicals not containing heteroatoms remains small because of structural limitations and synthetic issues.…”

19F electron nuclear double resonance (ENDOR) spectroscopy for distance measurements using trityl spin labels in DNA duplexes

“…It should be pointed out that orientation dependence has been documented for a TAM-labeled duplex at 94 GHz. 30 The 263 GHz EPR spectra were indicative of axial g-tensors, typical for trityls [38][39][40] (Fig. 3, left).…”
