Abstract Tris( N -octanoyl- dl -alaninato)europium(III) (Eu(oct-ala) 3 ) was newly prepared and it was found that the complex takes a stable glassy state by an evaporation of methanol from the solution, whereas tris(octanoato)europium(III) (Eu(octnt) 3 , i.e. europium soap) does not easily take a purely vitrified state. The luminescence intensity was larger and the spectrum was simpler in the glassy
摘要 Tris(N-octanoyl-dl-alaninato)europium(III) (Eu(oct-ala) 3 ) 是新制备的,发现该配合物通过从溶液中蒸发甲醇而呈现稳定的玻璃态,而tris (octanoato)europium(III)(Eu(octnt) 3 ,即铕皂)不容易采取纯玻璃化状态。与失透状态相比,玻璃态发光强度更大,光谱更简单。将 2,2'-联吡啶 (bpy) 或 4,4'-二壬基-2,2'-联吡啶 (dnbpy) 添加到 Eu(oct-ala) 3 会增加溶液中和通过添加 bpy,Eu(octnt) 3 变为稳定的玻璃态。
