Synthesis of a Net-Worked Strontium-O-Phenylene-S-Tellurium Hybrid Co-polymer Having a Two-Step Electron Transfer Nature

A strontium-O-phenylene-S-tellurium hybrid co-polymer was prepared by initially reacting 4-hydroxythiophenol with tellurium ethoxide, followed by a subsequent reaction with strontium isopropoxide, and the electronic behavior of the co-polymer was examined. From the results of ESR spectral examinations and ab initio calculations regarding the co-polymer models, the co-polymer was deduced to have a function of two-step electron transfer from the phenylene group to the strontium atom via the tellurium atom.

(ニオビウム-O-フェニレン-S)-(カドミウム-S-フェニレン-O)共重合体からなる焼成体の電子的挙動

The calcination of a (niobium-O-phenylene-S)- (cadmium-S- phenylene-O) hybrid copolymer under an argon atmosphere gave nano-sized Nb 2 O 5 / carbon clusters / CdS hybrid material. ESR spectral examinations suggest the possibility of an electron transfer in the process of Nb 2 O 5 → carbon clusters → CdS → carbon clusters.
