The single crystals of 9-phenyl-9-dibenzophosphole chalcogenides oxide (1), sulfide (2) and selenide (3)} and a mixed crystal of 2 and 3 have been prepared and characterized by X-ray diffraction analysis. Several intermolecular interactions such as π–π and Se–H were observed in the mixed crystal of 2 and 3. The mixed crystal of 2 and 3 exhibited enhanced phosphorescence compared to the pure constituent crystal (2 or 3) at low temperature.
我们制备了 9-苯基-9-二苯并膦酰基化合物氧化物(1)、
硫化物(2)和
硒化物(3)}的单晶体以及 2 和 3 的混合晶体,并通过 X 射线衍射分析对其进行了表征。在 2 和 3 的混合晶体中观察到一些分子间相互作用,如 π-π 和 Se-H。与纯成分晶体(2 或 3)相比,2 和 3 的混合晶体在低温下显示出更强的
磷光。
