NEW ORGANIC POLYMERS AND MOLECULES WITH VERY HIGH-SPIN STATES

A number of new organic tetraradicals with quintet ground states have been prepared. Along with their intrinsic significance, these structur es provide valuable tests of certain design principles for the constru ction of organic magnetic materials. The tetraradicals all follow the ''bis(TMM)'' approach, which promises to provide a wealth of informati on on spin preferences in organic structures. Efforts to prepare proto types of the polaronic ferromagnet are also described. Current work is aimed at evaluating the role of bipolaron formation in such systems, in an effort to increase the absolute spin concentration.
