Spontaneous ¹⁵N nuclear spin hyperpolarization in metal-free activation of parahydrogen by molecular tweezers

Autor: Sorochkina, K. (Kristina), Zhivonitko, V. V. (Vladimir V.), Chernichenko, K. (Konstantin), Telkki, V.-V. (Ville-Veikko), Repo, T. (Timo), Koptyug, I. V. (Igor V.)

The ability of frustrated Lewis pairs (FLPs) to activate H₂ is of significant interest for metal-free catalysis. The activation of H₂ is also the key element of parahydrogen-induced polarization (PHIP), one of the nuclear spin hyperpolarization t
