TL;DR: Variable temperature magnetic susceptibility measurements indicate that all four radicals exhibit S = 1/2 Curie-Weiss behavior over the temperature range 20-300 K, and at lower temperatures, the three selenium-based radicals display magnetic ordering.

TL;DR: A pair of isostructural bis-selenathiazolyl and bis-diselenazolyl radical conductors display weak (spin-canted) ferromagnetism with Tc values of 18 K and 27 K respectively.

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: Variable temperature conductivity measurements indicate that sequential replacement of sulfur by selenium leads to a progressive increase in conductivity and reduction in thermal activation energy.

TL;DR: Application of physical pressure to a ferromagnetic bisdiselenazolyl radical leads to a decrease in pi-stack slippage, and at higher pressures, as the pi-stacks become more nearly superimposed, the value of T(C) diminishes.
