C-Term Faraday Rotation in Low Symmetry tert-Butyl Substituted Polyferroceniums.

ABSTRACT: Molecular thin films are currently being investigated as candidate materials to replace conventional atomistic inorganic crystal-based Faraday rotators. High symmetry paramagnetic species have been reported to exhibit large Verdet constants via magnetic field splitting of degenerate ground states. However, lower symmetry open-shell species have not been extensively studied. Herein, we report the Faraday rotation of two poly di-tert-butylferroceniums with diphenylsilane and vinylene linkers. Thin films of oxidized poly[(1,1'-di-tert-butylferrocenyl)diphenylsilane] [poly(^tBu₂fc-SiPh₂)] displayed a 30% increase in maximum Verdet constant relative to the previously reported decamethylferrocen
