Spin Enhancement by Grinding of Cu‐TANC Coordination Polymer Crystals Showing d–π Interactions

Abstract

Bump ′n′ grind: A novel method for enhancing the ESR spin intensity by crystal grinding is proposed. Spin enhancement is observed (see picture) for the mortar-ground powder of the coordination polymer crystal {[CuI(TANC)I]}n. The spin intensity enhancement is likely due to the increased formation of spin-active species that are formed from crystal defects and crystal transformation.
