Abstract
In order to prepare organic magnetic materials, we have studied persistent high-spin polycarbenes. As a part of this research, 9-acrydyl(phenyl)diazomethane was synthesized and triplet carbene generated by photolysis of this diazo compound was characterized by spectroscopic means. Magnetic properties of photoproducts from a complex of 9-acrydyl(phenyl)diazomethane N-oxide and copper ion is also described.
