摘要:从苯并[ D ]噻唑-2-胺合成了基于8-溴苯并[4,5]噻唑并[3,2-C ] [1,3,5,2]恶二氮杂嘌呤核的荧光染料.新的硼配合物可以通过钯催化的(杂)芳基硼酸与suzuki-Miyaura的交叉偶联反应而得到有效修饰.该反应使得具有不同芳族取代基的1,3,5,2-恶二氮杂嘌呤发色团有价值的区域选择性后官能化.获得的目标配合物在有机溶剂中的溶液显示出高的荧光量子产率.在苯并噻唑单元上具有4-氰基苯基的化合物(ar = 4-C 6 H 4 Cn)在固态下表现出相对较高的荧光量子产率,为0.31.

摘要:Dyestuff dispersions and dyestuff solutions free from salt or at least having a low salt content are obtained in that the diazotization is carried out with addition of free dispersing agent acid to which, after the synthesis, either no basic agents are added or basic agents are added only up to a pH value of 3. The disclosed process gives dyestuff compositions of low salt content and results in readily dispersible dyestuffs when water insoluble dyestuffs are prepared and stable solutions when water soluble dyestuffs are prepared. The process is widely applicable and chemical constitution of the dyestuffs is conventional.
