F6] M = Fe, PP = dppe; M = Ru, PP = dppe or 2PPh3; L1 = 5-[3-(thiophen-2-yl)benzo[c]thiophenyl]thiophene-2-carbonitrile} have been synthesized and studied to evaluate their molecular quadratic hyperpolarizabilities. The compounds were fully characterized by NMR, FTIR and UV/Vis spectroscopy and their electrochemical behaviour studied by cyclic voltammetry. Quadratic hyperpolarizabilities (β) were
通式为[M(η5-C5H5)(PP)(L1)][PF6]的η5-单环戊二烯基(II)/钌(II)配合物M = Fe,PP = dppe;M = Ru,PP = dppe 或 2PPh3;L1 = 5-[3-(thiophen-2-yl)benzo[c]thiophenyl]thiophene-2-carbonitrile} 已被合成并研究以评估其分子二次超极化。这些化合物通过 NMR、FTIR 和 UV/Vis 光谱进行了充分表征,并通过循环伏安法研究了它们的电化学行为。二次超极化率 (β) 由超瑞利散射测量在 1500 nm 的基本波长确定。采用密度泛函理论计算来合理化这些复合物的二阶非线性光学特性。
