摘要：
Static second hyperpolarizability (gamma) of 1,4-phenylendiamine and 4,4'-diaminodiphenylamine in neutral and dicationic: states are investigated as model systems of dendritic structure. Expansion of pi-conjugation is found to significantly enhance the gamma value of the neutral model system. Charged defect in the present system is found to have a remarkable influence on the magnitude and sign of static gamma in the direction of pi-conjugation.
