通过非交替π-系统的电子和磁耦合是光子学和分子电子学研究中的一个非常感兴趣的领域,然而对于通过非交替π-系统的耦合知之甚少。本文研究了两个半醌基双自由基的磁交换耦合:1,3-SQ 2Fch是两个半醌基分别连接在二茂铁的同一个π-配体(一个非交替π-体系)的一位和三位上,而1,1′-SQ 2Fch是一个半醌基分别连接在二茂铁的两个π-配体上.
Electronic and magnetic coupling through nonalternant π-systems is an area of intense interest in photonics and molecular electronics research, yet relatively little is known regarding coupling through nonalternant π-systems. Herein we present magnetic exchange coupling in two semiquinone-based biradicals:1,3-SQ2Fchas two semiquinone radicals attached to the one- and three-positions of the same cyclopentadienyl ligand (a nonalternant π-system) of ferrocene, whereas1,1′-SQ2Fchas one semiquinone radical attached to each of the two cyclopentadienyl ligands of ferrocene.
