ABSTRACT:A ternary, scandium-phenylene-yttrium hybrid copolymer was synthesized by initially reacting 1,4-hydroquinone with scandium isopropoxide below À45 C followed by a second reaction with yttrium isopropoxide at room temperature. ESR spectral examinations and ab-initio calculations indicate that an electron transfer takes place initially from the phenylene group to the yttrium atom at a lower energy-level and then to the scandium atom at a higher energy-level, i.e. via two-step electron transportation.
