The reactions of various fluoroaromatics, C6F6−xHx, and C6F5X (X = C6F6, Cl, Me, NO2, CF3, COCl, CH2Br, OMe, and NH2) with lead(II) benzenethiolate in DMF have been examined. Lead thiolate acted as an excellent source of benzenethiolate anions and displacement of fluorine, chlorine or the nitro group was observed. The new products have been characterized by elemental analysis, and NMR (H−1 and F−19)
各种氟代芳烃,C 6 F 6-x H x和C 6 F 5 X(X = C 6 F 6,Cl,Me,NO 2,CF 3,COCl,CH 2 Br,OMe和NH 2的反应)中已检测了DMF中的苯硫醇铅(II)。硫醇铅是苯硫醇根阴离子的极好来源,并观察到了氟,氯或硝基的置换。这些新产品已通过元素分析,NMR(H-1和F-19),红外和质谱进行了表征。

The reactions of tin(II) benzenethiolate and p-toluenethiolate with various fluoroaromatics in DMF have been studied. Replacement of some of the aromatic fluorines by the thiolate group was observed. The tin(II) aromatic thiolates are comparable in reactivity in these reactions with lead(II) benzenethiolate. All new compounds have been characterized by elemental analysis, and NMR (H-1 and F-19) and

The aromatic thiolates of tin(II) and lead(II), M(SAr)2 (M = Sn, Pb) are readily prepared, and are stable at room temperature. The reactions of these thiolates Sn(SAr)2 (Ar = Ph, CH3C6H4) and Pb(SPh)2 with various fluoroaromatics have been studied in DMF. The Pb(SPh)2 was reasonably soluble in DMF, but Sn(SAr)2 was not very soluble, forming a suspension.
锡(II)和铅(II),M(SAr)2(M = Sn,Pb)的芳族硫醇盐易于制备,并且在室温下稳定。这些硫醇盐Sn(SAr)2(Ar = Ph,= CH 3 C 6 H 4)和Pb(SPh)2与各种氟代芳烃的反应已在DMF中进行了研究。Pb(SPh)2可溶于DMF,但Sn(SAr)2不太可溶,形成悬浮液。
Crystal Multi‐Conformational Control Through Deformable Carbon‐Sulfur Bond for Singlet‐Triplet Emissive Tuning
report that the singlet‐triplet emissive property can be profoundly regulated by crystal conformational distortions. Employing fluoro‐substituted tetrakis(arylthio)benzene luminophores as prototype, we found that couples of molecular conformations formed during different crystallizations. The deformable carbon‐sulphur bond essentially drove the distortion of the molecular conformation and varied the
There are numerous ways to achieve light-inducedself-assembly of goldnanoparticles, but most of them are through chemical reaction and slow. Ligands that can perform photoexcitation-induced aggregation were synthesized and modified onto goldnanoparticles. The leading functionalized nanoparticles exhibit highly efficient light-inducedself-assembly properties and show high-contrast color fading in
