  kind of basal diarylethene through an easy synthetic procedure was synthesized and characterized, and a Suzuki coupling reaction was frequently operated to obtain the diarylethenes derivatives with some vivid functional groups like bromo, amido and pyridine. Two methods for derivatives of these switches contain porphyrins were described. All of their spectroscopic and photochromic properties were studied

  通过一种简单的合成方法，对一种基础二芳基乙烯进行了合成和表征，并经常进行Suzuki偶联反应，以得到具有溴，酰胺基和吡啶等生动官能团的二芳烃衍生物。描述了两种用于这些开关的包含卟啉的衍生物的方法。他们的所有光谱和光致变色特性都经过了研究和比较。结果表明，闭合形式的π共轭体系的电子密度差异会影响UV-Vis光谱可见区的最大吸收。连接到卟啉的二噻吩基环戊烯可能会发出大量的发光信号，显示在二进制数据存储和智能材料的无损读出应用中可能使用的潜力。

  The direct arylation on the thienyl groups of a diarylethene with various aryl iodides efficiently provided arylated dithienylethenes under palladium catalysis. Unsymmetrically substituted dithienylethenes were also synthesized by this protocol. This procedure allows a rapid access to a variety of aryl-substituted dithienylethenes from a single substrate of a simple dithienylethene.
