抄録

Ab-initio LCAO CPHF (Coupled perturbed Hatree-Fock) study was performed to calculate the longitudinal cubic hyperpolarizability of the polyacetylene and polydiacetylene oligomers. The theoretical calculation successfully reproduced the experimentally measured non-resonant THG values of the hyperpolarizabilities of the polyacetylene oligomers. The effect of the conjugation pattern on the hyperpolarizability was investigated. The hyperpolarizability of the polyacetylene oligomers was found to be larger than that of the polydiacetylene ones. We could estimate the order of the nonlinearity of corresponding polymer systems from the results of oligomer calculations. These reconfirmed the spatial locality of the process in the nonlinear optical phenomena.
