Electronic behavior of calcined material obtained by microwave treatment of a tin-O-phenylene-O hybrid copolymer

Microwave treatment of a mixture of a tin-O-phenylene-O hybrid copolymer and graphite gave SnO2–carbon cluster–Sn composite material. The resulting composite materials were characterized by using XRD, SEM, EDX and TEM. ESR spectral examinations of the calcined materials reveal the possibility of a photo-responsive electron transfer in the process of carbon clusters → SnO2 and/or Sn. The calcined material was found to decompose 7,7,8,8-tetracyanoquinodimethane under light irradiation.
