| 摘 要： | 1 INTRODUCTIONAs a useful nonlinear optical material, the molecule must have a large second-order hyperpolarizability (β), and also must crystallize in a non-centrosymmetric structure to have a large ((2). Organic conjugated molecules with electronic donors and acceptors possibly have quite strong second-order NLO property. However, only a small percentage of the molecules with large β crystal-lize in useful non-centrosymmetric crystals. Marder and his co-worker carried out a simple an…
