Abstract
High-spin polycarbenes (1 and 2) have been designed by using the triplet diphenylcarbene molecule as a repeating unit. The corresponding polydiazo compounds were prepared and photolyzed in 2-methyltetra-hydrofuran matrices and in single crystals of a benzophenone host at cryogenic temperatures. The ESR fine structures and magnetic susceptibilities were measured and analyzed to show that the highest spin states were generated as the electronic ground state of the polycarbenes. Relevance of these results to organic ferromagnets is discussed.Keywords
