Deeper in the blue: A versatile procedure has been developed for the preparation of photoluminescent siloles and germoles by palladium‐catalyzed cross‐coupling of 2,2′‐diiodobiaryls with dihydrosilanes and ‐germanes. The dibenzosiloles and ‐germoles with ester moieties on the aromatic ring exhibited different emission wavelengths in the solution and crystalline states, attributable to the intermolecular
深入了解:已经开发了一种通用的程序,该程序通过钯催化2,2'-二碘联二芳基与二氢硅烷和锗烷的交叉偶联来制备光致发光的硅酮和芽。芳环上带有酯部分的二苯并甲硅烷基和锗锗烷在溶液和结晶态中显示出不同的发射波长,这归因于分子间的相互作用(见图)。
