| 英文摘要 | We have proved that the first - hyperpolarizabilities (beta(chi chi chi)) of the four stilbazolium - like dyes, which are trans - (N - methylpyrrol - 2 - yl) - 4 - (N - methyl - pyridinio) - stilbazolium iodide (MPPSI), trans - (pyrrol - 2 - yl) - 4 - (N - methyl - pyridinio) - stilbazolium iodide (PPSI), trans - (furan - 2 yl) - 4 - (N - methyl - pyridinio) - stilbazolium iodide (FPSI) and trans - (thiophene - 2 - yl) - 4 - (N methyl- pyridinio) - stilbazolium iodide (TPSI), can be linearly correlated with the electron excessivities of donors in fifteen solvents. Then we obtained the linearity correlation between the beta(chi chi chi) Of the dyes and the solvents polarity [ E-T(30)]. From the two linearity correlations we obtain three solvent factors eta, delta(A) and delta(D) for describing the solvents effects on the beta(chi chi chi): eta describes the sensitivity of the intramolecular electron transfer to the solvent polarity, delta(A) and delta(D) describe the accepting/donating ability of the acceptor/donor effected by the solvent polarity respectively. The delta(A) increases linearly, but the delta(D) is decreased linearly with increasing of the E-T(30). |
