通过芳族二胺与邻苯二醌/二乙基草酸酯缩合,然后用POCl 3氯化,制得一系列功能化的二氮杂和四氮杂戊酸酯,或通过钯催化的苯二胺与各种2,3-二氯喹喔啉的钯催化偶联。得到四氮杂trace烷(用MnO 2氧化后)。代表性实例包括卤化和硝化衍生物。讨论了这些氮杂环丁烷的光学性质及其分子结构和取代方式。重氮trace和四氮trace形成了两个不同的组,它们具有明显不同的电子结构和性质。此外,合成了1,2,3,4-四氟-6,11-双((三异丙基甲硅烷基)乙炔基)苯并[ b ]吩嗪,这是第一个报道的氟化重氮az。报告了该化合物的单晶X射线分析。
Enlarged acenothiadiazoles, which are easily prepared, display attractive optical and electrochemical properties. The annulation of thiadiazole to anthracene gives a stable material with optical properties similar to those of substituted pentacenes.
A synthetic strategy that allows the induction of twist angles of different sizes in 5,6,11,12,17,18‐hexaazatrinaphthylene (HATNA) chromophores is reported. The differenttwist angles are accompanied by measurable changes in the emission and electrochemical characteristics of HATNA.

The synthesis, optical, and electrochemical properties as well as solid-state structures of a series of alkynylated, benzannulated selenadiazoles are reported. This set of compounds Is compared to the lighter homologue series, the thiadiazoles. The selenadiazoles show head-to-head dimerization in the solid state, while packing of the thiadiazoles was dominated by the steric bulk of the side groups. The Se-N interaction is a supramolecular motif that should drive the effective self-assembly and modulate charge transport when these compounds are used as thin films in devices.

of an aromatic diamine with an ortho‐quinone/diethyloxalate followed by chlorination with POCl3 to give diazatetracenes or by palladium‐catalyzed coupling of a phenylenediamine with various 2,3‐dichloroquinoxalines to give tetraazatetracenes (after oxidation with MnO2). Representative examples included halogenated and nitrated derivatives. The optical properties of these azatetracenes were discussed
