摘要

By using weakly coordinating anions we succeeded in the stabilization and isolation of two Würster's blue-based diradicaloid dications with saturated spacers.Their geometries and electronic structures were investigated by various experiments in conjunction with DFT calculations.Both one-dimensional alkylate-bridged dications show considerable diradical character with spacer-dependent singlet-triplet energy gaps.One of them displays a much enhanced diradical character and could basically be viewed as a pure diradical with degeneracy of singlet and triplet states.
