TLDR
A wide range of heterocyclic sulfur-nitrogen and seleniumnitrogen radicals have been characterized in recent years as discussed by the authors, and the potential use of these radicals as building blocks for low-dimensional molecular conductors is outlined.Abstract:
A wide range of heterocyclic sulfur-nitrogen and selenium-nitrogen radicals have been characterized in recent years. Synthetic routes to these materials are summarized, and the modes of association which they exhibit in the solid state are illustrated. The potential use of these radicals as building blocks for low-dimensional molecular conductors is outlined, and some strategies for generating specific solid state architectures are explored. Recent attempts to prepare conductive materials from custom-built bifunctional 1, 2, 3, 5-dithia- and diselenadiazolyls are described.read more

TL;DR: Variable-temperature magnetic susceptibility measurements indicate that antiferromagnetic exchange between radicals along the pi-stacks increases with pi-stack slippage, and the origin of the dramatically different magnetic behavior across the series has been explored in terms of a direct through-space mechanism by means of DFT calculations on individual pairwise exchange energies.

TL;DR: The variability of the conductivity with crystal growth conditions is examined in this article, with the best crystals showing room temperature conductivities of ∼1000 Ω−1·cm−1 along the chain axis, increasing by a factor of 11 to 13 down to 20°K and decreasing only slightly at lower temperatures.
