摘要：

First-order hyperpolarizabilities beta of a sequence of dimethylaminocyanopolyphenyl oligomers are measured by using the electric field induced second harmonic generation technique. High beta values (up to 55x10(-30) esu at zero frequency) are reported to be in-keeping with transparency in the visible and near UV spectral range. The behaviour of beta related to the number of phenyl units is compared to calculated hyperpolarizabilities and discussed in terms of trade-off between intramolecular charge transfer and the non-coplanarity between the benzene rings.
