Fullerene derivatives resulting from an unexpected Diels-Aldercycloaddition have been obtained by reaction of trans-2-stilbenecarboxaldehyde derivatives with N-methylglycine and C60.

donor-pi-donor derivatives containing phenyl, naphthyl, and anthryl groups as the pi-center and heterocyclicrings as the conjugation bridge have been synthesized and their one- and two-photon spectroscopic properties and photostability were determined. These compounds show bathochromic shifts in the absorption and emission spectra, larger two-photon cross-section, and enhancedphotostability in comparison to

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。

A conjugated poly(p-phenylene vinylene) is manufactured by means of CVD and using simple monomers. Such a polymer is particularly adaptable for use as an active layer in electroluminescent devices, such as a light-emitting diode.
