Abstract

PMMA and PET thin films doped with (t-Bu)₄VOPc {(t- Bu)₄VOPc PMMA and (t-Bu)₄VOPc PET} and PMMA thin film doped with (t-bu)₁. ₄VOPc {(t-Bu)₁. ₄ VOPc PMMA} were prepared on glass substrate by coating (t-Bu)₄VOPc PMMA and (t-Bu)₄VOPcPET were treated with dichloroethane vapor in a desiccator at room temperature. On the other hand, (t-Bu)₁. ₄VOPc PMMA was treated with dichloroethane and chloroform vapor in the desiccator at room temperature. The (t-Bu)₁. ₄VOPc PMMA and (t-Bu)₄VOPc PMMA thin films showed SHG and THG after vapor treatment but (t-Bu)₄VOPc PET thin film did not. These suggest that the degree of swelling by dichloroethane vapor are different between PMMA and PET. In other words, the aggregation of (t-Bu₄) VOPc occurs more easily in PMMA than in PET. The THG of (t-Bu)₁. ₄VOPc PMMA thin film is larger than that of a (t-Bu)₄VOPc PMMA thin film. This means that the molecular size of (t-Bu)₁. ₄VOPc is smaller than that of the size of (t-Bu)₄VOPc.
