由交替的Tl 2 Me 4（thf）2和O2 C6 H（Me）（t-Bu）−（t-Bu）（Me）HC 6 O2（SQ-SQ）亚基组成的聚合物链已经通过用Tl（Me）2（3，6-DBSQ）处理母体双（苯醌）而形成。相邻环的甲基取代基之间的空间相互作用导致环平面之间的二面角为51.5°，并且双（半醌）桥连配体的自由基中心之间存在强磁交换。
Polymeric chains consisting of alternating Tl2Me4(thf)2and O2C6H(Me)(t-Bu)−(t-Bu)(Me)HC6O2(SQ−SQ) subunits have been formed by treating the parent bis(benzoquinone) with Tl(Me)2(3,6-DBSQ). Steric interactions between methyl substituents of adjacent rings result in a dihedral angle of 51.5° between ring planes and strong magnetic exchange between radical centers of the bis(semiquinone) bridging ligand.
