摘要

Abstract The insulating role of the bicyclo [2.2. 2] octane fragment has been theoretically evaluated by comparing the electronic coupling parameter (V ab) in 1, 4-bis (ferrocenyl) benzene (1) and 1, 4-bis (ferrocenyl) bicyclo [2.2. 2] octane (2). The geometries were optimized by DFT and an extended Hückel calculation was performed to evaluate V ab by the dimer splitting method. The calculations showed a 12-fold decrease of the electronic ...
