The disorder of the thienyl ring and〓 groups in 11, 12 and the disorder of water in the packing of 14 may be responsible for their triboluminescent activities.Ⅲ. A dinuclear triboluminescent complex,〓(15)(where TTA=2- thenoyltrifluoroacetone, PyO=N-oxide pyridine), was synthesised and its crystal structure and triboluminescence spectrum were determined.

X-射線結(jié)構(gòu)分析表明，四個配合物中的銪原子均呈現(xiàn)出八配位的四方反錐幾何構(gòu)型。11、12及13均為有對稱中心結(jié)構(gòu)配合物欧美日韩在在线视频，11、12中的噻吩環(huán)及〓的無序以及配合物14晶胞中水分子的無序可能對它們的摩擦發(fā)光活性起了很重要的作用加勒比在线精品观看。

The characteration of 15 will may provide a new pathfor searching new triboluminescent complexes. The triboluminescence maximum of 15is similar to that of its photoluminescence. The disorder of the thienyl rings and 〓groups in 15 may be responsible for its triboluminescent activity.

Eu的距離為4.2137(9)〓天天插天天碰。兩個橋聯(lián)O原子與兩個Eu構(gòu)成一平面四邊形，∠Eu(1)-O(7)-Eu(1A)和∠O(7)-Eu(1)-O(7A)分別為117.84(14)°和62.18(14)°6080无码吃奶在线观看视频。15的摩擦發(fā)光光譜與其光致發(fā)光光譜很類似人人爱人人操人人摸人人干人人爱，表明它們有相同的激發(fā)態(tài)。15的摩擦發(fā)光活性可能與其結(jié)構(gòu)中噻吩環(huán)及〓的無序有關(guān)超碰在线免费公开干。

The Stille coupling reaction between 8 iodo 9 benzyl 9H purine and RSnBu 3 (R=vinyl,2 thienyl,2 furyl,phenylethynyl and phenyl) was studied using (Ph 3P) 2PdCl 2 as catalyst and DMF as solvent.

Using thienyl stannane and palladium-catalyzed, 1,4-di(5'-carbaldehyde-thiophen-2'-yl)-2,5-dioctyloxy-benzene was synthesized by four steps, the structure was determined by NMR, IR and elemental analysis.

由于目標產(chǎn)物(5)本身具有多芳環(huán)共軛體系，其熒光效應(yīng)相當強烈在线免费观看毛片网站，在氯仿溶液中紫外-可見吸收和熒光發(fā)射的最大波長分別為413nm和477nm，固態(tài)熒光發(fā)射波長為504nm

Eight half-sandwich titanium complexes (S1-S8) with pendant thienyl group were synthesized. These complexes with MAO were tested in ethylene conversion.
