nonlinear optical material. 12-nitro-4,7-bis(2-ferrocenylvinyl)[2.2]paracyclophane (1) and 12-nitro-4,5,7,8-tetrakis(2-ferrocenylvinyl)[2.2]paracyclophane(2) have been synthesized by pd-catalyzed coupling reactions of vinylferrocene with the precursor cyclophanes 9 and 13, respectively. The absorption and electrochemicalproperties of 1 and 2 are also described.

3]paracyclophane-bridged binuclearruthenium vinyl complexes have been synthesized by insertion reactions of [RuHCl(CO)(PPh3)3] with the appropriate dialkynes. The products have been characterized by physico-chemical and spectroscopic methods. In addition, the structure of one complex has been determined by X-ray crystallography. Electrochemical studies have shown that all of the substituted complexes exhibit smaller
通过 [RuHCl(CO)(PPh3)3] 与合适的二炔的插入反应,合成了一系列取代的二硫杂 [3.3] 对环芳桥双核钌乙烯基配合物。产品已通过物理化学和光谱方法表征。此外,一种复合物的结构已通过 X 射线晶体学确定。电化学研究表明,相对于未取代的复合物,所有取代的复合物都表现出更小的 ΔE 值。光致发光研究表明,除甲氧基外,所有被检测的取代基都起到“猝灭剂”的作用。
