blue phosphorescent organometallic compounds of group 15, M[p-C6H4(N-7-azain)]3 with M = P (1), Sb (2), Bi (3) and 7-azain = 7-azaindolyl, have been synthesized from the reaction of MCl3 with Li[p-C6H4(N-7-azain)]. The crystal structures of these new compounds have been determined by single-crystal X-ray diffraction, which revealed that the group 15 elements in all three complexes are in a trigonal-pyramidal
第15组新的蓝色磷光有机金属化合物,M [ p -C 6 H 4(N -7-azain)] 3,M = P(1),Sb(2),Bi(3)和7-azain = 7-氮杂吲哚基,是由MCl 3与Li [ p -C 6 H 4(N -7-氮杂)]反应合成的。这些新化合物的晶体结构已通过单晶X射线衍射测定,结果表明,所有三个配合物中的第15组元素均处于三角金字塔形环境中,其键角为C-MC围绕中心原子从参照图1至图3,归因于MC键的s性质的减小和中心原子的尺寸增加。所有这三种化合物均为蓝色发光。在77 K下观察到化合物1的荧光和磷光发射(λmax = 371 nm,λmax = 488 nm)。相比之下,在77 K时,仅观察到化合物2和3的磷光(λmax = 483 nm)。2 ; 3时λmax = 478 nm),这归因于重原子效应的增加。实验数据和分子轨道计算(受限的Hartree-Fock方法
